	@section section_overview Overview

	Final Platform Layer is a Single-Header-File cross-platform <b>C99</b>/<b>C++</b> development library, designed to abstract the underlying platform to a simple and easy-to-use API - providing low-level access to the operating system and hardware devices.<br>
	<br>
	The main focus is rapid game/media/simulation development, so the default settings will create a window, set up an OpenGL rendering context, and initialize audio playback on any platform.<br>
	<br>
	FPL supports the platforms <b>Windows</b>/<b>Linux</b>/<b>Unix</b> for the architectures <b>x86</b>/<b>x64</b>/<b>arm</b>.<br>
	<br>
	The only dependencies are built-in operating system libraries and a <b>C99</b> or <b>C++/11</b> compliant compiler.<br>
	<br>
	It is released under the @subpage page_license "MIT License". This license allows you to use FPL freely in any software, for private or commercial usages.<br>

	@section section_intro Introduction to FPL

	@subsection subsection_intro_whatisfpl What is FPL?

	Final Platform Layer is a Single-Header-File cross-platform <b>C99</b>/<b>C++</b> development library designed to abstract the underlying platform to a very simple and easy-to-use API - providing low level access to:<br>
	- Single Window creation and handling
	- Graphics Software or Hardware Rendering initialization.
	- Asynchronous Playback of Audio Samples
	- Accessing Input Devices (Keyboard, Mouse, Gamepad)
	- IO handling (Files, Directories, Paths)
	- Multithreading (Threads, Mutexes, Signals, Conditions)
	- String conversions UTF8 <-> WideString
	- Allocating Memory
	- Retrieve Hardware & OS Informations
	
	The main focus is game/media/simulation development, so the default settings will create a window, set up an OpenGL rendering context, and initialize audio playback on any platform.<br>
	<br>
	Final Platform Layer is released under the @subpage page_license "MIT License". This license allows you to use FPL freely in any software.<br>

	@subsection subsection_intro_whatissingleheaderfilelibrary What is a single-header-file library and why is FPL based on that?
	A single header file library (as the name implies) is a development library designed to be one file only.<br>
	Such a file contains the header (API) and the body (Implementation) in one file but separated and controlled by compiler conditions.<br>
	Due to the nature of a single-header-file library, all the sources come with it - so it is most likely licensed by a public domain license.<br>
	Also, such libraries mostly do not require any dependencies at all, to making them more friendly to the user.<br>
	This makes it easy to use the library however you want (with source, Static-linked, As a DLL, Private use only).<br>
	<br>
	So, why then is FPL based on that?<br>
	<br>
	Because normal libraries typically have a lot of disadvantages:
	- Force you to link to it dynamically or statically
	- Force you to use build-systems just to compile it
	- Requires specific CRT versions which make linking a madness
	- Require or come with a ton of dependencies
	- Are closed source or use an incompatible license
	- Takes ages to compile because of its hundreds of translation units

	@subsection subsection_intro_supported_platforms Which platforms are supported by FPL?
	- Windows (x86/x64)
	- Linux (x86/x64/arm)
	- Unix/BSD (x86/x64, partially)

	For more details see the page: @subpage page_support_status
	
	@subsection subsection_intro_supported_compilers Which compilers are supported by FPL?
	FPL should compile on any <b>C99</b> or <b>C++/11</b> compliant compiler, such as <b>MSVC</b>, <b>GCC</b>, <b>Clang</b>, etc.

	@section section_usage_setup Download & Setup

	@subsection subsection_usage_setup_download Download

	- You download the latest <a href="https://github.com/f1nalspace/final_game_tech/blob/master/final_platform_layer.h">"final_platform_layer.h"</a> file.
	- Drop it into your C/C++ project and use it in any place you want.

	@subsection subsection_usage_setup_setup Setup?
	- No setup required

	@section section_usage_requirements Requirements

	FPL uses built-in operating system libraries and requires a <b>C99</b> or <b>C++/11</b> compliant compiler.<br>
	Depending on the compiler and platform - linking to one system library may be needed:

	@subsection usage_requirements_win32 Win32
	- Link against "kernel32.lib"

	@subsection usage_requirements_unix Unix/Linux
	- Link against "libld.so"
	- Compiler parameter "-pthread" (<a href="https://gcc.gnu.org/onlinedocs/gcc/Preprocessor-Options.html#Preprocessor-Options">GCC Preprocessor Options</a>)

	@subsection usage_requirements_crt C-Runtime optional
	By default, FPL uses the CRT (C-Runtime-Library) for functions such as vsnprintf(), but its usage is optional.<br>
	To learn how to use FPL without the CRT more details, see the page @subpage page_nocrt

	@section section_usage_howtouse How to use FPL?
	In your main C/C++ translation-unit include the header file and call @ref fplPlatformInit() and @ref fplPlatformRelease() respectively:

	@code{.c}
	#define FPL_IMPLEMENTATION
	#include "final_platform_layer.h"

	int main(int argc, char **argv) {
		// Initialize the platform with default settings
		if (fplPlatformInit(fplInitFlags_All, fpl_null)) {

			// your code goes here

			// Release the platform
			fplPlatformRelease();
			return 0;
		} else {
			return -1;
		}
	}
	@endcode

	You can then include this file in any other C/C++ source or header file as you would with any other header file.

	Provide the typical main entry point with at least the initialization and release of the platform:

	@section section_usage_multiple_translation_units How to use FPL in multiple translation units?

	To use FPL in multiple translation units, it is recommended to create a separated "final_platform_layer.c" file in the same directory FPL is located and define the implementation there only:<br>

	<b>final_platform_layer.c</b>:
	@code{.c}
	#define FPL_IMPLEMENTATION
	#define FPL_NO_ENTRYPOINT // Disable the entry point inclusion
	#include "final_platform_layer.h"
	@endcode

	This way FPL implementation is compiled once and can be used everywhere.<br>
	<br>
	In your main translation-unit, you just include the entry point only using the preprocessor define **FPL_ENTRYPOINT**.

	<b>main_translation_unit.c</b>:
	@code{.c}
	#define FPL_ENTRYPOINT // Integrate entrypoint only
	#include "final_platform_layer.h"
	@endcode

	@section section_usage_static_library How to use FPL in a static library?

	To use FPL as a/in static library you do the same steps required for using FPL in multiple translation units.
	See @ref section_usage_multiple_translation_units for more details.

	@section section_usage_codecomments How do I get the code-documentation to show up in the IDE?

	When FPL is compiled directly in your main translation-unit, some IDE's read the comments from the implementation bodies instead of from the header definitions.<br>
	This is wrong, but we can't help it. Those editors just are not designed for single-header-file libraries :-(

	But do not fear, you can get the comments to show up in your IDE properly, just compile the implementation into a separated translation-unit only.<br>
	This way the IDE will parse the comments from the API declaration only. See @ref section_usage_multiple_translation_units for more details.

	@section section_usage_options Options
	See @subpage page_compiler_options for all compile-time options.

	@page page_category_initialization Initialization & Release
	@tableofcontents

	@section section_category_initialization_include Include the Library

	In one of your C/C++ translation units include this:

	@code{.c}
	#define FPL_IMPLEMENTATION
	#include "final_platform_layer.h"
	@endcode

	You can then include this file in any other C/C++ source or header file as you would with any other header file.

	@section section_category_initialization_entrypoint Entry Point

	Simply provide the typical main entry point:<br>

	@code{.c}
	int main(int argc, char **argv) {
		// code goes here
	}
	@endcode

	@section section_category_initialization_simple Initialization with default settings

	Call @ref fplPlatformInit() (inside the main @ref section_category_initialization_entrypoint) and provide the desired @ref fplInitFlags and @ref fpl_null as arguments, to initialize FPL with default settings.

	@code{.c}
	int main(int argc, char **argv) {
		// With defaults (Window, Video, Audio)
		fplPlatformInit(fplInitFlags_All, fpl_null);

		// Only audio
		fplPlatformInit(fplInitFlags_Audio, fpl_null);

		// Only window and audio
		fplPlatformInit(fplInitFlags_Window | fplInitFlags_Audio, fpl_null);

		return 0;
	}
	@endcode

	It is recommended to always pass a pointer to a @ref fplSettings structure, but you can leave it as @ref fpl_null as well.<br>
	Call @ref fplSetDefaultSettings() with a pointer to your local settings container to initialize the settings container with default values.

	@section section_category_initialization_with_settings Initialization with custom settings

	Call @ref fplPlatformInit() (inside the main @ref section_category_initialization_entrypoint) and provide the desired @ref fplInitFlags and a pointer to @ref fplSettings argument to initialize FPL with custom settings.

	@code{.c}
	// Overwrite settings
	fplSettings settings;
	fplSetDefaultSettings(&settings);

	// or
	fplSettings settings = fplMakeDefaultSettings();

	// change the settings here

	fplPlatformInit(fplInitFlags_All, &settings);
	@endcode

	@section section_category_initialization_release Releasing the Platform

	Call @ref fplPlatformRelease() when you are done. This will release all internal resources.<br>
	
	@code{.c}
	fplPlatformRelease();
	@endcode

	@section section_category_initialization_result Result/Error checking

	There is no guarantee that @ref fplPlatformInit() will always work with the fplSettings you specified, maybe the audio device does not support a sample rate of 1337 kHz or your video card does not support OpenGL version 3.7 - who knows.<br>
	<br>
	Therefore, you should always check the result using @ref fplGetPlatformResult() !<br>
	This returns a @ref fplPlatformResultType enum which is @ref fplPlatformResultType_Success when initialization succeeded.<br>
	<br>
	Also, you should release the platform when the initialization was successful only!<br>
	If something goes wrong the remaining resources are already cleaned up by FPL automatically.<br>
	<br>
	Also, you should use @ref fplGetLastError() to print out the actual error when the initialization fails!<br>

	<b>Very bad:</b> (But will work)
	@code{.c}
	fplPlatformInit(fplInitFlags_All, fpl_null);

	// your code here

	fplPlatformRelease();
	@endcode

	<b>Bad:</b> (But will work)
	@code{.c}
	if (fplPlatformInit(fplInitFlags_All, fpl_null)) {
		// your code here
	}
	fplPlatformRelease();
	@endcode

	<b>Good:</b>
	@code{.c}
	if (fplPlatformInit(fplInitFlags_All, fpl_null)) {
		// your code here
		fplPlatformRelease();
	}
	@endcode

	<b>Better:</b>
	@code{.c}
	if (fplPlatformInit(fplInitFlags_All, fpl_null)) {
		// your code here
		fplPlatformRelease();
	} else {
		const char *errStr = fplGetLastError();
		fplConsoleFormatError("FPL-ERROR: %s\n", errStr);
	}
	@endcode

	<b>Much better:</b>
	@code{.c}
	if (fplPlatformInit(fplInitFlags_All, fpl_null)) {
		// your code here
		fplPlatformRelease();
	} else {
		fplPlatformResultType initResult = fplGetPlatformResult();
		const char *initResultStr = fplPlatformGetResultName(initResult);
		const char *errStr = fplGetLastError();
		fplConsoleFormatError("FPL-ERROR[%s]: %s\n", initResultStr, errStr);
	}
	@endcode

	See the @subpage page_category_errorhandling page for more details about error handling.
	
	@section section_category_initialization_tips Tips
	After releasing FPL you can call @ref fplPlatformInit() again if needed - for example: Finding the proper audio device, Testing for OpenGL compatibility, etc. may require you to call @ref fplPlatformInit() and @ref fplPlatformRelease() multiple times.<br>
	For more details see @subpage page_gettingstarted <br>
	<br>
	Optionally you can use @ref fplMakeDefaultSettings to create a default filled @ref fplSettings structure, which can be directly used for @ref fplPlatformInit()<br>
	<br>
	If needed you can get the currently used @ref fplSettings configuration by calling @ref fplGetCurrentSettings()
*/

/*!
	@page page_category_errorhandling Error handling
	@tableofcontents

	@section section_category_errorhandling_getplatformresult Check platform result

	Use @ref fplGetPlatformResult() to query the current platform result.<br>
	This is useful to check if @ref fplPlatformInit() was already called or not.
	Also, this is useful to see which system failed in @ref fplPlatformInit() .

	Example:
	@code{.c}
	fplPlatformResultType resultType = fplGetPlatformResult();
	switch (resultType) {
		case fplPlatformResultType_NotInitialized:
			printf("Platform is not initialized yet!");
			break;
		case fplPlatformResultType_FailedAudio:
			printf("The audio system failed to initialize: %s", fplGetLastError());
			break;
	}
	@endcode

	@note You may combine @ref fplGetPlatformResult() with @ref fplGetLastError, to get a more understanding of what exactly went wrong.

	@section section_category_errorhandling_getlatest Get latest error

	In case something goes wrong you can always call @ref fplGetLastError() - at any time, regardless if it is initialized or not.<br>
	This either returns an empty string indicating everything is fine or a formatted string with a valid error message.<br>

	Example:
	@code{.c}
	const char *errStr = fplGetLastError();
	// Do something with the error string
	@endcode

	@section section_category_errorhandling_count Was there an error?

	If you just want to check if there was an error, you can call @ref fplGetErrorCount() to use the number of errors as a condition.<br>

	Example:
	@code{.c}
	if (fplGetErrorCount()) {
		// Print out the error message
	}
	@endcode

	@section section_category_errorhandling_getbyindex Get error by index

	Use @ref fplGetErrorByIndex() to get a error string for the given index in range @ref fplGetErrorCount() .

	Example:
	@code{.c}
	size_t errorCount = fplGetErrorCount();
	if (errorCount > 0) {
		const char *lastError = fplGetErrorByIndex(errorCount - 1);
		// Do something with the last error
	}
	@endcode
	
	@section section_category_errorhandling_clear Clearing the errors

	Errors will never be cleared by FPL! You have to do this yourself using @ref fplErrorsClear() .<br>

	Example:
	@code{.c}
	fplClearErrors();
	@endcode
*/

/*!
	@page page_category_logging Debug & Logging
	@tableofcontents

	@section section_category_logging_logging Logging

	FPL has an internal logging system built-in.<br>
	By default this logging system is disabled, but you can enable it by defining the preprocessor definition **FPL_LOGGING** before including the FPL header file.<br>
	<br>
	You can change the maximum log-level using @ref fplSetMaxLogLevel() . By default, this is set to @ref fplLogLevel_Critical which means that only system-wide critical errors will be reported.<br>
	When the logging system is enabled, you can get or change the configuration using @ref fplGetLogSettings() / @ref fplSetLogSettings() respectively.<br>

	This configuration has two modes, a mode in which you can define one writer for every log level and one mode in which you have a writer for each log-level separately. By default, it uses the first mode, which is one writer for all log-levels.<br>
	To change this behavior, you can set the preprocessor definition **FPL_LOG_MULTIPLE_WRITERS**. With this, you can change the logging in every detail.<br>

	A log writer can be configured to log to multiple logging-targets.<br>
	<br>
	FPL supports up-to 4 log-targets:
	- Console standard output
	- Console error output
	- Debug console output
	- Custom callback

	See @ref fplLogWriterFlags and @ref fplLogSettings for more details.

	@subsection subsection_category_logging_logging_example_console_only Example: Log everything to the standard console only

	@code{.c}
	fplLogSettings logSettings = fplZeroInit;
	logSettings.maxLevel = fplLogLevel_All;
	logSettings.writers[0].flags = fplLogWriterFlags_StandardConsole;
	fplSetLogSettings(&logSettings);
	@endcode

	@subsection subsection_category_logging_logging_example_errors_only Example: Log all errors to the error console only

	Log all errors, warnings, and criticals to the default error console.
	
	@code{.c}
	fplLogSettings logSettings = fplZeroInit;
	logSettings.maxLevel = fplLogLevel_Error;
	logSettings.writers[0].flags = fplLogWriterFlags_ErrorConsole;
	fplSetLogSettings(&logSettings);
	@endcode

	@subsection subsection_category_logging_logging_example_custom Example: Log all errors to a custom logging function
	
	Log all errors, warnings, and criticals to a custom callback defined as @ref fpl_log_func_callback .

	@code{.c}
	static void MyLogFunction(const fplLogLevel level, const char *message) {
		// ...
	}

	fplLogSettings logSettings = fplZeroInit;
	logSettings.maxLevel = fplLogLevel_Error;
	logSettings.writers[0].flags = fplLogWriterFlags_Custom;
	logSettings.writers[0].custom.callback = MyLogFunction;
	fplSetLogSettings(&logSettings);
	@endcode

	@section section_category_logging_debug Debug

	@subsection subsection_category_logging_debug_break Forced Breakpoint

	You can force to stop on a specific line of code always by calling the function @ref fplDebugBreak() .<br>
	It works exactly like a breakpoint, but it will always break until you remove the call to it.

	Example:
	@code{.c}
	// ... code
	fplDebugBreak(); // Debugger will always stop here
	// ... code
	@endcode

	@subsection subsection_category_logging_debug_out Output to the Debug-Console

	On IDE's such as visual studio you can use @ref fplDebugOut() or @ref fplDebugFormatOut() to print out stuff in the console directly in your IDE.<br>

	Example:
	@code{.c}
	// Basic output
	fplDebugOut("Debug-Values:\n");

	// or

	// Formatted output
	fplDebugFormatOut("Value of X: %f\n", xValue);
	@endcode

	@section section_category_assertions Assertions

	FPL contains runtime and compile-time assertion macros, which you can use to ensure application state consistency.
	
	@subsection subsection_category_assertions_runtime Runtime assertion

	You can use the macro function @ref fplAssert() to trigger an runtime assertion in a debug-build.<br>
	When the condition in your assertion is false, your application will crash immediately.

	Example:
	@code{.c}
	// When i is less than 5 this code will trigger a assertion that will crash your application immediately.
	fplAssert(i >= 5);

	// Will trigger a assertion when the "str" pointer is null.
	fplAssert(str != fpl_null);
	@endcode

	@warning When you are building in release-mode runtime-time assertions are compiled out entirely - unless you have specific **FPL_FORCE_ASSERTIONS**!
	@warning Do not call any important functions inside an assertion statement, because it will get compiled out eventually.

	@subsection subsection_category_assertions_static Compile-time / static assertion

	You can use the macro function @ref fplStaticAssert() to trigger a compile-time assertion in a debug-build.<br>

	Example:
	@code{.c}
	typedef struct myStruct {
	  int a;
	  float b;
	} myStruct;

	// Will throw a compile error when "myStruct" is not of total size of 8-bytes
	fplStaticAssert(sizeof(myStruct) == 8);
	@endcode

	@warning When you are building in release-mode compile-time assertions are compiled out entirely - unless you have specific **FPL_FORCE_ASSERTIONS**!
	@warning Do not call any important functions inside an assertion statement, because it will get compiled out eventually.

	@subsection subsection_category_assertions_enabledisable Enable/Disable assertions

	In Debug-Mode assertions are enabled, unless you have specified **FPL_NO_ASSERTIONS**.<br>
	In Release-Mode assertions are disabled, unless you have specified **FPL_FORCE_ASSERTIONS**.<br>
	<br>

	@section section_window_basics_init Initialization

	To create a window, you add the @ref fplInitFlags_Window flag to the @ref fplInitFlags argument in the @ref fplPlatformInit() call.<br>
	It makes no sense to create a window alone, so we combine it at least with something else, like for example a video context or audio playback.<br>

	@code{.c}
	fplPlatformInit(fplInitFlags_Window | fplInitFlags_Video, fpl_null);
	@endcode

	@section section_window_basics_mainloop Main loop

	After you initialize FPL with a window, you have to create some sort of a loop to keep the window open until you close them.<br>
	This is required because the operating systems use an event-based system to communicate with the window and your application.<br>
	If no communication happens with your window and your app, the window will no longer be responsive - so make sure to communicate properly.<br>
	<br>
	To solve this, you have to use @ref fplWindowUpdate() and @ref fplPollEvent() respectively.
	<br>
	First, you need to call @ref fplWindowUpdate() for every 'tick' for your application. This will clear the internal event queue and update input devices properly.<br>
	After that, you have to poll all events from the operating systems event queue using @ref fplPollEvent() .<br>

	@code{.c}
	while (fplWindowUpdate()) {
		fplEvent ev;
		while (fplPollEvent(&ev)) {
			// ... Handle event here
		}
	}
	@endcode

	See @subpage page_category_window_events for more details.<br>

	@attention All window-based calls are required to be executed from the main-thread only!

	@section section_window_basics_shutdown Shutdown the window

	Simply call @ref fplWindowShutdown to shutdown the window, while it is still running.<br>
	<br>
	You can also query the running state of the window by calling @ref fplIsWindowRunning() .<br>

	@note The window is not immediately shut-down, one tick of window/input events may still be executed after that.<br>To forcefully terminate the window, use @ref fplPlatformRelease() instead.

	Call @ref fplPollEvent() in a while-loop inside your actual main-loop with a pointer to a @ref fplEvent argument to poll the next event from the OS event queue.<br>
	Each event is translated into the @ref fplEvent argument which you can handle or not. If there are no events left, the function returns false.

	All available event types are stored in the @ref fplEventType enumeration.

	@section section_category_window_events_handle_event_type Handle the event data

	All relevant event data are stored in fields that match the lowercase @ref fplEventType name.<br>
	Each event structure has another type field to check for the actual type (Key-Down, Mouse-Move, Window-Resize, etc.).<br>

	@subsection subsection_category_window_events_handle_event_buttonstate Button states

	All mouse/keyboard or gamepad button states are descriped as a @ref fplButtonState.<br>
	<br>
	To detect a non-repeatable button press, you simply compare against @ref fplButtonState_Press.<br>
	To detect a repeatable button press, you simply compare against @ref fplButtonState_Repeat.<br>
	To detect a non button press, you simply compare against @ref fplButtonState_Release.<br>
	<br>
	If you just want to know if a key is pressed or hold-down, just do a greater equals comparison of @ref fplButtonState_Press and you are golden.

	@subsection subsection_category_window_events_handle_event_type_mouse Mouse events

	Mouse event data are stored in the @ref fplMouseEvent structure.<br>
	A mouse event contains either a single button click/release or a mouse wheel change or a position change.<br>

	@subsection subsection_category_window_style_style_decorated Decoration (Border, Titlebar)

	By default, a window is decorated. This means that it has a border, a title bar, and can be moved by the user.<br>
	If you enable window decorations, your window will have a border and a title bar always.<br>
	<br>
	Use @ref fplIsWindowDecorated() to determine if the window has decoration enabled or not.<br>
	Use @ref fplSetWindowDecorated() to enable/disable the window decoration.<br>

	<b>Example:</b>
	@code{.c}
	// Enable window decoration
	fplSetWindowDecorated(true);

	// Disable window decoration
	fplSetWindowDecorated(false);

	// Toggle window decoration
	fplSetWindowDecorated(!fplIsWindowDecorated());

	@note You can overwrite the default decoration behavior by changing the value in @ref fplWindowSettings.isDecorated from the @ref fplSettings.window field at startup.

	@subsection subsection_category_window_style_floating Floating (Always on top)

	By default, a window is not in floating mode. This means when another window gets focus, your window loses its focus.<br>
	If you set your window to floating instead, your window will always be on top of others.<br>
	<br>
	Use @ref fplIsWindowFloating() to determine if the window is floating or not.<br>
	Use @ref fplSetWindowFloating() to enable/disable the window floating.<br>

	<b>Example:</b>
	@code{.c}
	// Enable window floating
	fplSetWindowFloating(true);

	// Disable window floating
	fplSetWindowFloating(false);

	// Toggle window floating
	fplSetWindowFloating(!fplIsWindowFloating());

	@note You can overwrite the default floating behavior by changing the value in @ref fplWindowSettings.isFloating from the @ref fplSettings.window field at startup.

	@subsection subsection_category_window_style_resizable Resizeable

	By default, a window is resizeable. This means you can resize your window however you like.<br>
	<br>
	Use @ref fplIsWindowResizable() to determine if the window is resizable or not.<br>
	Use @ref fplSetWindowResizeable() to enable/disable the window resizing.<br>

	<b>Example:</b>
	@code{.c}
	// Enable resizing of the window
	fplSetWindowResizeable(true);

	// Disable resizing of the window
	fplSetWindowResizeable(false);

	// Toggle window resizing mode

	@section section_category_window_style_size Getting/Changing the size/position

	@subsection subsection_category_window_style_size_pos Window position

	By default, a window uses either the default position from the platform or a fixed location of 0x0 screen units.<br>
	<br>
	Use @ref fplSetWindowPosition() to change the position of the window
	Use @ref fplGetWindowPosition() to retrieve the current absolute window position from the top-left corner

	<b>Example:</b>
	@code{.c}
	// Retrieve absolute window position
	fplWindowPosition curPos;
	if (fplGetWindowPosition(&curPos)) {
		// Do something with the window position
	}

	// Change window absolute position to 0x0
	fplSetWindowPosition(0, 0);
	@endcode

	@subsection subsection_category_window_style_size_window Window size

	By default, a window is created using either the default size of the platform or a fixed size of 400x400 screen units.<br>
	<br>
	Use @ref fplSetWindowSize() to change the size of the area of the window.<br>
	Use @ref fplGetWindowSize() to get the size of the area of the window.<br>

	<b>Example:</b>
	@code{.c}
	// Retrieve window inner/client size
	fplWindowSize curSize;
	if (fplGetWindowSize(&curSize)) {
		// Do something with the client size
	}

	// Change window size to fit 800x600 screen units inside the client area
	fplSetWindowSize(800, 600);
	@endcode

	@note You can overwrite the default window size by changing the value in @ref fplWindowSettings.windowSize from the @ref fplSettings.window field at startup.
	@note Changing the window size changes the total size of the window - when decorations are enabled.

	@subsection subsection_category_window_style_size_fullscreen Fullscreen size

	By default, the window is created in non-fullscreen mode, using @ref fplWindowSettings.windowSize from the @ref fplSettings.window or
	the default window size. See @ref subsection_category_window_style_size_window for more details.<br>
	<br>
	Use @ref fplSetWindowFullscreenSize() to enable/disable fullscreen for the window with a given **size** and a **color depth** with support of switching the screen-resolution if needed.<br>
	Use @ref fplSetWindowFullscreenRect() to enable/disable fullscreen for the window with a given **size** and a **position** without changing the screen-resolution.<br>
	Use @ref fplIsWindowFullscreen() to determine if the window is in fullscreen mode or not.<br>

	<b>Enable fullscreen example:</b>
	@code{.c}
	// Enable fullscreen on the nearest desktop
	fplEnableWindowFullscreen();

	// or

	To initialize either software or hardware video output, you have to set the @ref fplInitFlags_Video flag in the @ref fplPlatformInit() call and ensure that video is not disabled by a preprocessor directive **FPL_NO_VIDEO**.<br>

	Also setting the @ref fplInitFlags_Video flag ensures that the @ref fplInitFlags_Window flag is appended automatically.<br>

	@subsection category_video_general_init_default Default video output

	If you don't specify any settings then the video backend is automatically detected, depending on your operating system and supported hardware and software.<br>
	By default, this is most likely be legacy OpenGL - which is supported on almost every video card on any OS.<br>
	<br>
	But this is not the recommended way to initialize video output, because you are responsible for handling any video output yourself.<br>

	@code{.c}
	if (fplPlatformInit(fplInitFlags_Video)) {
		// ... your code here
	}
	@endcode

	@subsection category_video_general_init_setting_driver Setting the video backend

	It is recommended to set at least the video backend manually, to ensure that you get either initialized with that backend properly or an error when your configuration is not supported.<br>
	<br>
	You do that by simply setting the @ref fplVideoBackendType field in your @ref fplVideoSettings structure which is included in the @ref fplSettings structure to the @ref fplPlatformInit() call.
	
	@code{.c}

	@note There is no guarantee that vertical synchronization is supported by your video device or selected backend.
	@note Software video output does not support vertical synchronisation!

	@section category_video_general_disable Disable unneeded video backends

	To compile out certain video backends, you simply specify the **FPL_NO_VIDEO_[Name of the video backend]** preprocessor directive.<br>
	But the @ref fplVideoBackendType in question is never removed from the enumeration - keep that in mind!<br>

	Example (Disable OpenGL video backend):

	@code{.c}
	#define FPL_NO_VIDEO_OPENGL
	#define FPL_IMPLEMENTATION
	#include <final_platform_layer.h>
	@endcode

	@section category_video_general_disable_all Disable all Video Output

	#define FPL_NO_VIDEO
	#define FPL_IMPLEMENTATION
	#include <final_platform_layer.h>
	@endcode

	@note Keep in mind that this is not useful for window-based applications!
	@note If you writing a console application and don't want any video output whatsoever you set the **FPL_NO_WINDOW** which automatically disables any video devices as well.

	@tableofcontents
	
	@section section_category_video_vulkan_init Initialize Vulkan
	
	Initializing Vulkan is different than initializing other graphics APIs such as OpenGL, but FPL helps you in the first steps.
	
	The very first thing you need is a Vulkan Instance (<a href="https://www.khronos.org/registry/vulkan/specs/1.2-extensions/man/html/VkInstance.html">VkInstance</a>).
	
	Secondly you require a Vulkan Surface (<a href="https://www.khronos.org/registry/vulkan/specs/1.2-extensions/man/html/VkSurfaceKHR.html">VkSurfaceKHR</a>) to present the graphical result to the screen.
	
	FPL can create the Instance and the Surface for you.
	
	The surface creation is mandatory, but an exiting instance can optionally be passed to the @ref fplSettings structure if needed.
	
	- @ref section_category_video_vulkan_init_full
	- @ref section_category_video_vulkan_init_surfaceonly
	
	@section section_category_video_vulkan_init_full Create a Vulkan Instance and a Surface
	
	First you have to create a @ref fplSettings structure and initialize it with default settings using @ref fplSetDefaultSettings().
	
	Second you set the @ref fplVideoSettings.backend to @ref fplVideoBackendType_Vulkan .

	We can reference the @ref fplVulkanSettings type stored in @ref fplGraphicsApiSettings.vulkan for convenience usage later.
	
	@code{.c}
	fplSettings settings;
	fplSetDefaultSettings(&settings);
	
	// Reference of the video settings
	fplVideoSettings *videoSettings = &settings.video;

	// Forcing the video backend to Vulkan
	videoSettings->backend = fplVideoBackendType_Vulkan;
	
	// Reference of the vulkan settings for later usage
	fplVulkanSettings *vulkanSettings = &videoSettings.graphics.vulkan;

	Continue with @ref section_category_video_vulkan_usage
	
	@section section_category_video_vulkan_init_surfaceonly Create a Vulkan Surface from an existing Instance
	
	If you already have a Vulkan Instance (VkInstance), you can simply pass that to the @ref fplVulkanSettings.instanceHandle field and initialize FPL with @ref fplPlatformInit():
	
	@code{.c}
	VkInstance yourVulkanInstance;
	
	fplVulkanSettings *vulkanSettings = &videoSettings.graphics.vulkan;

	vulkanSettings->instance = yourVulkanInstance; // Pass in your vulkan instance to FPL

		// ... Vulkan Surface is created now and are ready to use
	}
	@endcode
	
	Continue with @ref section_category_video_vulkan_usage
	
	@section section_category_video_vulkan_usage Vulkan Usage
	
	After you have created a Vulkan Instance and a Surface, you can query it by calling @ref fplGetVideoSurface() directly after @ref fplPlatformInit():
	
	@code{.c}
	if (fplPlatformInit(fplInitFlags_All, &settings)) {
		// Get video surface
		const fplVideoSurface *surface = fplGetVideoSurface();
		fplAssert(surface != fpl_null);
		
		// Get the VkInstance and VkSurfaceKHR
		VkInstance instanceHandle = (VkInstance)surface->vulkan.instanceHandle;
		VkSurfaceKHR surfaceHandle = (VkSurfaceKHR)surface->vulkan.surfaceKHR;
		fplAssert(instanceHandle != VK_NULL_HANDLE);
		fplAssert(surfaceHandle != VK_NULL_HANDLE);

		// ... continue the Vulkan initialization process
	}
	@endcode

	After that, the typical Vulkan process continues:
	- Finding the physical device (<a href="https://www.khronos.org/registry/vulkan/specs/1.2-extensions/man/html/VkPhysicalDevice.html">VkPhysicalDevice</a>)
	- Creating a logical device (<a href="https://www.khronos.org/registry/vulkan/specs/1.2-extensions/man/html/VkDevice.html">VkDevice</a>)

	@page page_category_video_software Software Output
	@tableofcontents

	@section section_category_video_software_init Initialize a software backbuffer

	To initialize software rendering output, you simply set the @ref fplInitFlags_Video flag in the @ref fplPlatformInit() call and change the video backend type to @ref fplVideoBackendType_Software.<br>
	Call @ref fplGetVideoBackBuffer() to get access to the pixel data.

	@code{.c}
	fplSettings settings;
	fplSetDefaultSettings(&settings);
	fplVideoSettings &videoSettings = settings.video;

	// Forcing the video backend to be software
	videoSettings.backend = fplVideoBackendType_Software;

	if (fplPlatformInit(fplInitFlags_Video, &settings)) {
		// Video software backbuffer is ready
		fplVideoBackBuffer *videoBackBuffer = fplGetVideoBackBuffer();
	}
	@endcode

	@section section_category_video_software_usage Usage

	To use the software backbuffer you simply access the @ref fplVideoBackBuffer from the @ref fplGetVideoBackBuffer() function and update the pixels as needed.

	@subsection subsection_category_video_software_present Presenting your frame

	Call @ref fplVideoFlip() to draw the pixels from the backbuffer to the window.<br>
	Its recommend to call this after each draw call of your frame at the end of the main-loop.

	@subsection subsection_category_video_software_drawing Drawing

	Drawing is done by manually changing the pixels in the @ref fplVideoBackBuffer.pixels field.<br>
	Each pixel is stored as 32-bit with 4 RGBA components in little-endian (AA BB GG RR).<br>
	Lines are stored in top-down order - meaning that position "0" in the @ref fplVideoBackBuffer.pixels field is always the top-left corner of the bitmap!<br>
	To calculate the actual position for the current line, you simply multiply your Y-Index with the @ref fplVideoBackBuffer.lineWidth field.

	<b>Example (Filling all pixels to purple):</b>

	@code{.c}
	fplVideoBackBuffer *backBuffer = fplGetVideoBackBuffer();
	for (uint32_t y = 0; y < backBuffer->height; ++y) {
		uint32_t *p = (uint32_t *)((uint8_t *)backBuffer->pixels + y * backBuffer->lineWidth);
		for (uint32_t x = 0; x < backBuffer->width; ++x) {
			uint32_t color = 0xFFFF00FF;
			*p++ = color;
		}
	}
	@endcode

	@subsection subsection_category_video_software_outrect Limiting the output rectangle (Stretching vs non-stretched)

	To force the pixels to be shown in a fixed rectangle you simply enable the @ref fplVideoBackBuffer.useOutputRect field and update the @ref fplVideoBackBuffer.outputRect as needed.<br>
	This mimics a "viewport" which is similar to OpenGLs glViewport().<br>
	<br>
	If you don't use this feature all pixels are fully stretched to the current window area always!

	@note This viewport should not be greater than the actual window area dimension!

	<b>Example (Resize window event):</b>
	@code{.c}
	static fplVideoRect ComputeLetterbox(int windowWidth, int windowHeight, int backWidth, int backHeight) {
		return {};
	}
	fplVideoBackBuffer *backBuffer = fplGetVideoBackBuffer();
	backBuffer->useOutputRect = true;
	while (fplWindowUpdate()) {
		fplEvent ev;
		while (fplPollEvent(&ev)) {
			if (ev.type == fplEventType_Window) {
				if (ev.window.type == fplWindowEventType_Resized) {
					fplVideoRect newRect = ComputeLetterbox(ev.window.width, ev.window.height, backBuffer->width, backBuffer->height); // ... Compute new rectangle here (Letterbox or something)
					backBuffer->outputRect = newRect;
				}
			}
		}

		// ... Modify the pixels here (Draw call)

		fplVideoFlip();
	}
	@endcode

	<b>Example (Always before the draw call):</b>
	@code{.c}
	fplVideoBackBuffer *backBuffer = fplGetVideoBackBuffer();
	backBuffer->useOutputRect = true;
	while (fplWindowUpdate()) {
		fplEvent ev;
		while (fplPollEvent(ev)) {}

		fplWindowSize windowArea = fplGetWindowSize();
		fplVideoRect newRect = ComputeLetterbox(windowArea, backBuffer->width, backBuffer->height); // ... Compute new rectangle here (Letterbox or something)
		backBuffer->outputRect = newRect;

		// ... Modify the pixels here (Draw call)

		fplVideoFlip();
	}
	@endcode

	@subsection subsection_category_video_software_resize Resizing the backbuffer

	By default, the video backbuffer is automatically resized when the dimension of the window area changes.<br>
	If you want to manually do this, you disable this feature in the @ref fplVideoSettings.isAutoSize field - in the @ref fplSettings.video configuration section.<br>
	<br>
	Call @ref fplResizeVideoBackBuffer() with a new width and height as an argument, to force the backbuffer to be resized to the new dimension.<br>

	@warning Do not call this method while you are modifying pixels!

	@section section_category_video_software_notes Notes

	- There is no software rendering functions built-in! If you want to draw for example a circle, you have to roll out your drawCircle() function - which may use Bresenham as its base or something.<br>
	- Vertical synchronization is not supported for software video backends!

	To initialize audio playback with default settings, you have to include the @ref fplInitFlags_Audio flag in the @ref fplPlatformInit() call and ensure that audio is not disabled by a preprocessor directive **FPL_NO_AUDIO**.<br>

	@code{.c}
	fplSettings settings;
	fplSetDefaultSettings(&settings);

	@endcode

	@subsection subsection_category_audio_general_default_init_clientcallback Setting the client callback

	Next is to specify the client user callback which gets invoked regularly when the audio device requires new samples to play.<br>
	This @ref fpl_audio_client_read_callback "client callback" can be set up in the @ref fplAudioSettings.clientReadCallback field from the @ref fplSettings.audio or changed by calling @ref fplSetAudioClientReadCallback() :<br>

	@code{.c}
	static uint32_t MyAudioPlaybackCallback(const fplAudioFormat *nativeFormat, const uint32_t frameCount, void *outputSamples, void *userData) {

	if (fplPlatformInit(fplInitFlags_Audio, &settings)) {
		// ... your code here
	}
	@endcode

	@note This step must be done before you can start playing the audio!
	@note You can specify a user data pointer that gets passed to the client callback as well.

	@section section_category_audio_general_custom_init Custom Settings

	You can change several audio settings (Sample rate, Number of Channels, Format, Channel layout, etc.) before initializing the audio playback like this:<br>

	@code{.c}
	fplSettings settings;
	fplSetDefaultSettings(&settings);
	fplAudioSettings &audioSettings = settings.audio;
	audioSettings.clientReadCallback = MyAudioPlaybackCallback;
	audioSettings.userData = // ... pointer to some user data
	fplAudioFormat &audioDeviceFormat = audioSettings.deviceFormat;
	audioDeviceFormat.sampleRate = 48000;
	audioDeviceFormat.channels = 2;
	audioDeviceFormat.layout = fplAudioChannelLayout_Stereo;
	audioDeviceFormat.type = fplAudioFormatType_F32;
	if (fplPlatformInit(fplInitFlags_Audio, &settings)) {
		// ... your code here
	}
	@endcode

	@note Please see the @ref section_category_audio_general_notes for possible limitations!
	
	@note If the @ref fplAudioChannelLayout does not match the number of channels, the layout are automatically detected by the number of channels.

	@section section_category_audio_general_choosing_driver Choosing the audio backend

	By default, FPL uses the first available audio backend which is supported on your platform.<br>
	If you want to force FPL to use a certain audio backend, you can do this by changing the @ref fplAudioSettings.backend field in the @ref fplAudioSettings structure:<br>

	@code{.c}
	fplSettings settings;
	fplSetDefaultSettings(&settings);
	fplAudioSettings &audioSettings = settings.audio;

	// Forcing to use the DirectSound audio backend
	audioSettings.backend = fplAudioBackendType_DirectSound;

	if (fplPlatformInit(fplInitFlags_Audio, &settings)) {
		// ... your code here
	}
	@endcode

	It is recommended to use the default @ref fplAudioBackendType_Auto which tries all audio backends until a suitable is found.

	@warning If your platform/system does not support the desired backend, the audio and platform initialization will fail!

	@section section_category_audio_general_autoplay Automatic play/stop of audio samples playback

	By default, FPL starts the playback of audio samples automatically, but only when @ref fplAudioSettings.clientReadCallback was set!<br>
	Also audio playback will be stopped when @ref fplPlatformRelease() is called as well.<br>
	<br>
	You can disable this behavior by changing the fields @ref fplAudioSettings.startAuto and fplAudioSettings.stopAuto in the @ref fplAudioSettings configuration respectively.<br>

	@section section_category_audio_general_manualplay Manual play/stop of audio samples playback

	For manual control of start/stop playback of audio samples use the following functions:
	- @ref fplPlayAudio() to start requesting and play audio samples.
	- @ref fplStopAudio() to stop the audio playback.

	@warning Please ensure that @ref fplStopAudio() is called before @ref fplPlatformRelease() always!

	@section section_category_audio_general_notes Notes

	There is no guarantee that you get the desired audio format you specified back!<br>
	You should always check the @ref fplAudioFormat "nativeAudioFormat" in your client callback and convert/write the correct samples the audio device expects!<br>
	<br>
	For more details see the page: @subpage page_category_audio_writesamples <br>

	A channel map is a table of channel indices to a @ref fplAudioChannelType.
	
	If you have a @ref fplAudioChannelLayout_Stereo or even @ref fplAudioChannelLayout_Mono, you can simply use the default indices (0|1) or just zero for mono.
	
	As soon as you have more than two channels, you have to get the @ref fplAudioChannelMap from the current audio backend and map your source channel indices.
	You can get the current @ref fplAudioChannelMap by calling @ref fplGetAudioChannelMap().

	- Target format (S16, S24, F32, etc.)
	- Target number of channels (1 = Mono, 2 = Stereo, 4 = Quad or Surround, 6 = 5.1 etc.)
	- Target sample rate (22050, 44100 Hz, 48000 Hz, etc.)
	- Number of audio frames required
	- If your sound device uses more than two channels, you have to call @ref fplGetAudioChannelMap() to get the channel mapping for each audio channel.

	All these informations are provided by the @ref fpl_audio_client_read_callback callback function.<br>
	<br>
	The required format are stored as an argument to your call, see @ref fplAudioFormat or call @ref fplGetAudioHardwareFormat() to get this information before the audio playback is started.

	@section section_category_audio_writesamples_functions Useful functions

	To help with sample computation there are several functions available:

	- @ref fplGetAudioHardwareFormat()
	- @ref fplGetAudioBufferSizeInFrames()
	- @ref fplGetAudioBufferSizeInMilliseconds()
	- @ref fplGetAudioBackendName()
	- @ref fplGetAudioFormatName()
	- @ref fplGetAudioSampleSizeInBytes()
	- @ref fplGetAudioFrameSizeInBytes()
	- @ref fplGetAudioBufferSizeInBytes()

	@section section_category_audio_writesamples_s16 Writing 16-bit signed integer samples

	@code{.c}
	static uint32_t MyAudioPlaybackCallback(const fplAudioFormat *nativeFormat, const uint32_t frameCount, void *outputSamples, void *userData) {
		uint32_t result = 0;
		if (nativeFormat->type == fplAudioFormatType_S16) {
			int16_t *outSamples = (int16_t *)outputSamples;
			for (uint32_t frameIndex = 0; frameIndex < frameCount; ++frameIndex) {
				for (uint32_t channelIndex = 0; channelIndex < nativeFormat->channels; ++channelIndex) {
					*outSamples++ = // ... Getting a sample for the current frame/channel
					++result;
				}
			}
		} else {
			// ... handle other formats here
		}
		return result;
	}
	@endcode

	@section section_category_audio_writesamples_notes Important Notes

	@note FPL does not provide any functionality for doing any kind of DSP or format conversion!<br>
	@note You are responsible for filling out the samples in the correct format your audio device expects!
	@note Repect the audio channel map, otherwise samples may be played back on the wrong speaker!

	@page page_category_memory_handling Memory handling
	@tableofcontents

	FPL provides a couple of functions to allocate/set/clear memory for you.<br>
	You are free to use it as you like, but you can use malloc(), free() as well if you want to.

	@section section_category_memory_handling_normal Default/Unaligned memory allocation

	@subsection subsection_category_memory_handling_normal_allocate Allocate (n)-bytes of memory

	To allocate a block of contiguous memory, you simply call @ref fplMemoryAllocate() with the number of bytes you want to allocate.<br>
	This will return a pointer you can start to write into.

	@code{.c}
	// Allocate 4MB of memory
	void *myMemory = fplMemoryAllocate(fplMegaBytes(4));
	// ...

	// or you can allocate the type directly

	// Allocate a bunch of int's
	int *intArray = (int *)fplMemoryAllocate(sizeof(int) * 100000);
	intArray[0] = 42;
	// ...
	@endcode

	@note This function does nothing more than calling the proper operating-system function such as **VirtualAlloc()** or **mmap()** .
	@attention The memory is not guaranteed to be aligned, but depending on the OS it may be aligned to something.
	@warning Do not write before this pointer, otherwise, you may overwrite meta-informations required for releasing the memory later on.

	@subsection section_category_memory_normal_free Free memory

	To free memory, you simply call @ref fplMemoryFree() with the base pointer of your memory, and that's it.

	@code{.c}
	// Free a memory block allocated by fplMemoryAllocate
	fplMemoryFree(myMemory);
	@endcode

	@warning Do not call this function with a pointer allocated from @ref fplMemoryAlignedAllocate() , otherwise, you will corrupt memory!

	@subsection subsection_category_memory_handling_normal_datalayout Data layout of default/unaligned memory

	Here you can see the full data-layout for a default/unaligned memory block:
	
	| 0 or 4/8 bytes for x86/x64                   | 0 or 4/8 bytes for x86/x64     | n-bytes                 |
	|----------------------------------------------|--------------------------------|-------------------------|
	| **Optional size of the entire memory block** | **Optional padding**           | **Memory of the data**  |

	@note On Linux/Unix the size and small padding are stored before the actual data, because **munmap()** requires a size as a parameter as well. 

	@section section_category_memory_handling_aligned Custom aligned memory allocation

	@subsection subsection_category_memory_handling_aligned_allocate Allocate custom aligned (n)-bytes of memory

	To allocate a **custom aligned** block of contiguous memory, you simply call @ref fplMemoryAlignedAllocate() with the number of bytes you want to allocate and the custom alignment.<br>
	This will return a guaranteed aligned pointer you can start to write into.

	@code{.c}
	// Allocate a bunch of 4x4 matrices aligned by 16-bytes
	typedef struct Mat4f {
		float m[16];
	} Vec4f;
	Mat4f *matrices = (Mat4f *)fplMemoryAlignedAllocate(sizeof(Mat4f) * 128, 16);
	// ...
	@endcode

	@note The size of the memory block may be greater than the size you requested, due to alignment padding and meta-informations.
	@attention The alignment parameter must be a power-of-two based value, otherwise, the function will fail.
	@warning Do not write before this pointer, otherwise you will overwrite meta-informations required for releasing the memory later on.

	@subsection subsection_category_memory_handling_aligned_free Free aligned memory

	To free aligned memory you simply call @ref fplMemoryAlignedFree() with the base pointer of your aligned memory and that's it.

	@warning Do not call this function with a pointer allocated from @ref fplMemoryAllocate() , otherwise, you will corrupt memory!

	@subsection subsection_category_memory_handling_aligned_datalayout Data layout of aligned memory

	Here you can see the full data-layout for a aligned memory block:
	
	| 4/8 bytes for x86/x64           | Alignment * 2 bytes   | n-bytes                                                                       |
	|---------------------------------|-----------------------|-------------------------------------------------------------------------------|
	| **Address of the base-pointer** | **Alignment padding** | \ref subsection_category_memory_handling_normal_datalayout "Data layout"      |

	@section section_category_memory_handling_ops Memory operations

	@subsection subsection_category_memory_handling_ops_clear Clear (n)-bytes of memory

	Call @ref fplMemoryClear() to clear a memory block starting from the base-pointer with a given size.

	@code{.c}
	// Clear 4-KB of memory to zero, starting by the given memory address
	fplMemoryClear(myMemory, 4096);

	// or

	// Clear a struct
	fplMemoryClear(myStructPtr, sizeof(*myStructPtr));

	// or

	// Clear a fixed sized array
	fplMemoryClear(myArray, sizeof(myArray));
	@endcode

	@note This operation is executed in 8-bytes, 4-bytes, 2-bytes sized chunks to improve performance.

	@subsection subsection_category_memory_handling_ops_set Overwrite (n)-bytes of memory with a given value

	Call @ref fplMemorySet() to overwrite a memory block starting from the base-pointer with a given size and the given value.

	@code{.c}
	// Overwrites 1000 bytes of memory with a 8-bit value
	fplMemorySet(myMemory, 0xAB, 1000);
	@endcode

	@note This operation is executed in 8-bytes, 4-bytes, 2-bytes sized chunks to improve performance.

	@subsection subsection_category_memory_handling_ops_copy Copy (n)-bytes of memory to another memory location

	To copy (n)-bytes of memory you simply call @ref fplMemoryCopy() with the source and destination pointer and the number of bytes you want to copy.

	@code{.c}
	// Copy parts of memory into another memory
	// void *destMemory was already allocated before
	size_t numberOfBytesToCopy = fplKiloBytes(10);
	fplMemoryCopy(sourceMemory, numberOfBytesToCopy, destMemory);
	@endcode

	@note This operation is executed in 8-bytes, 4-bytes, 2-bytes sized chunks to improve performance.

	| @ref fplClearStruct | Clears the given struct pointer to zero                    |
	| @ref fplCopyStruct  | Copies the source struct data into the destination pointer |
	| @ref fplArrayCount  | Returns the number of elements in fixed sized array        |
	| @ref fplOffsetOf    | Returns the byte-offset to a field in a struct             |
	| @ref fplKiloBytes   | Converts the given kilobytes value into bytes              |
	| @ref fplMegaBytes   | Converts the given megabytes value into bytes              |
	| @ref fplGigaBytes   | Converts the given gigabytes value into bytes              |

	@section section_category_io_paths_constants Path constants

	FPL provides a couple of path constants you can use, if needed:<br>
	| Name | Description |
	|-|-|
	| @ref FPL_MAX_PATH_LENGTH | Defines the maximum length of any path|
	| @ref FPL_MAX_FILENAME_LENGTH | Defines the maximum length of a single filename without path|
	| @ref FPL_PATH_SEPARATOR | Defines the path separator character|
	| @ref FPL_FILE_EXT_SEPARATOR | Defines the file extension separator character|

	@note All length constants include the null-terminator character as well, so you don't have to add one to the length when using!

	@section section_category_io_paths_utils Utilities

	@subsection subsection_category_io_paths_utils_pathcombine Combining paths

	Use @ref fplPathCombine() to combine multiple parts of a path to build one single path from it.<br>
	Unfortunately, this function requires you to pass the number of parts you want to combine :-(<br>
	If you know how to get the count of the variadic arguments (va_list) in C99, please contact me or write a GitHub issue! Thanks.<br>

	<b>Example:</b>
	@code{.c}
	const char *assetsRootPath = ...
	char textureAssetFilePath[FPL_MAX_PATH_LENGTH];
	if (fplPathCombine(textureAssetFilePath, fplArrayCount(textureAssetFilePath), 3, assetsRootPath, "textures", "mytexture.png") != fpl_null) {
		// ... Do something with the textureAssetFilePath
	}

	char tempPath[1024];
	fplPathCombine(tempPath, fplArrayCount(tempPath), 3, "One", "Another", "Last");
	// POSIX tempPath = One/Another/Last
	// Win32 tempPath = One\Another\Last
	@endcode

	@note This is the recommended way to construct any kind of path because it will handle path separators correctly.
	@note This function is designed to be compatible with .NET <b>Path.Combine()</b>.
	@warning Do not pass the wrong number of maximum arguments as a third-argument, otherwise, your application may end crashing horribly.

	@subsection subsection_category_io_paths_utils_extractfilepath Extracting the file path

	Use @ref fplExtractFilePath() to extract the directory from the given path.<br>
	<br>
	Using this on a path with a file will extract the path where the file is stored.<br>
	Using this on a directory path will extract the path of the parent directory.<br>

	<b>Example:</b>
	@code{.c}
	const char *inputPath = ...
	char newPath[FPL_MAX_PATH_LENGTH];
	if (fplExtractFilePath(inputPath, &newPath, fplArrayCount(newPath)) != fpl_null) {
		// ... Do something with the newPath
	}
	@endcode

	@note This function is designed to be compatible with .NET <b>Path.GetDirectoryName()</b> or <b>ExtractFilePath()</b> on Delphi/FreePascal.<br>
	@note The original path is not altered in any way, therefore the source argument is defined as const.
	@warning Do not use manually constructed source paths with fixed path separators such as <b>/</b> or <b>\\</b>, otherwise you will lose platform independence! Use @ref fplPathCombine() to build new paths from multiple paths if needed.
	@warning The return value of @ref fplExtractFilePath returns the pointer to the last-written character and <b>NOT</b> the pointer to the first character!

	@subsection subsection_category_io_paths_utils_extractfilename Extracting the file name

	Use @ref fplExtractFileName() to extract the filename from any path.<br>
	Using this on a full or relative file-path will extract the name of the file.<br>
	Using this on a directory path will extract the name of the last directory in the path.<br>

	<b>Example:</b>

	const char *inputFilePath = ...
	const char *fileName = fplExtractFileName(inputFilePath);

	// ... Do something with the fileName

	// Results:
	// /my/path/to/the/file.ico -> file.ico

	@subsection subsection_category_io_paths_utils_extractfileext Extracting the file extension

	Use @ref fplExtractFileExtension() to extract the file extension from a path.<br>
	This will return anything starting from the last found file extension separator @ref FPL_FILE_EXT_SEPARATOR to the very end of the path - containing the starting dot.<br>
	Using this on a path or filename will get you just the file extension if there is any.<br>

	<b>Example:</b>
	@code{.c}
	const char *inputFilePath = ...
	const char *fileExt = fplExtractFileExtension(inputFilePath);

	// ... Do something with the fileExt

	@section section_category_io_paths_get Retrievement of paths

	@subsection subsection_category_io_paths_get_home Getting the home directory path

	Use @ref fplGetHomePath() to retrieve the home directory path for the current user.<br>
	<br>
	On a POSIX based system this will most likely return something like <b>&quot;/usr/home/the_username_in_question&quot;</b><br>
	On a Win32 based system this will most likely return something like <b>&quot;c:\\Users\\TheUsernameInQuestion&quot;</b><br>

	<b>Example:</b>
	@code{.c}
	char homePath[FPL_MAX_PATH_LENGTH];
	fplGetHomePath(&homePath, fplArrayCount(homePath));
	// ... Do something with the homePath
	@endcode

	@note There is no guarantee that this path ends with a trailing path separator, such as <b>/</b> on POSIX or <b>\\</b> on Win32! If needed use @ref fplEnforcePathSeparator to force a path separator on always.
	@warning The return value of @ref fplGetHomePath returns the pointer to the last-written character and <b>NOT</b> the pointer to the first character!

	@subsection subsection_category_io_paths_get_exepath Get executable file path

	Use @ref fplGetExecutableFilePath() to retrieve the full-path to your current executable.<br>
	<br>
	On a POSIX based system this will most likely return something like <b>&quot;/some/path/../my_application&quot;</b><br>
	On a Win32 based system this will most likely return something like <b>&quot;c:\\Some\\Path\\..\\MyApplication.exe&quot;</b><br>

	<b>Example:</b>
	@code{.c}
	// Get executable file path
	char exeFilePath[FPL_MAX_PATH_LENGTH];
	fplGetExecutableFilePath(&exeFilePath, fplArrayCount(exeFilePath));

	// Get executable directory path
	char appPath[FPL_MAX_PATH_LENGTH];
	if (fplExtractFilePath(exeFilePath, &appPath, fplArrayCount(appPath)) != fpl_null) {
		// ... Do something with appPath
	}
	@endcode

	@note There is no guarantee that this path ends with a trailing path separator, such as <b>/</b> on POSIX or <b>\\</b> on Win32! If needed use @ref fplEnforcePathSeparator to force a path separator on always.
	@note The name of the executable is always included in the path and will contain the file extension if there is one.
	@warning The return value of @ref fplExtractFilePath returns the pointer to the last-written character and <b>NOT</b> the pointer to the first character!

	@section section_category_io_paths_traversing Directory Traversing

	FPL provides a powerful and easy directory traversal API, to find either files, directories, or both using a wildcard matching system.

	@subsection subsection_category_io_paths_traversing_findfiles Finding files by wildcard

	Use @ref fplDirectoryListBegin() to start finding files in a path.<br>
	If this function succeeds, the result for the first match is written into the @ref fplFileEntry structure.<br>
	<br>
	After this you repeatly call @ref fplDirectoryListNext(), to get the next match into @ref fplFileEntry structure - until the function returns false.<br>

	<b>Example:</b>
	@code{.c}
	const char *sourcePath = ...
	fplFileEntry fileEntry;
	size_t fileCount = 0;

	// Find all .so files (For-loop style)
	fileCount = 0;
	for(bool hasEntry = fplDirectoryListBegin(sourcePath, "*.so", &entry); hasEntry; hasEntry = fplDirectoryListNext(&entry)) {
		// ... do something with entry.name
		++fileCount;
	}

	// Find all .so files (While style)
	fileCount = 0;
	if (fplDirectoryListBegin(sourcePath, "*.so", &entry)) {
		// The first file was found
		// ... do something with entry.name
		++fileCount;

		// Loop until no file is found
		while (fplDirectoryListNext(&entry)) {
			// ... do something with entry.name
			++fileCount;
		}
	}

	// Find all .so files (For-loop style, break out after reaching a limit of maximum allowed files)
	size_t maxFileCount = ...
	fileCount = 0;
	for(bool hasEntry = fplDirectoryListBegin(sourcePath, "*.so", &entry); hasEntry; hasEntry = fplDirectoryListNext(&entry)) {
		if (fileCount < maxFileCount) {
			// ... do something with entry.name
		} else {
			// Release resources, when we exit out the iteration
			fplDirectoryListEnd(&entry);
			break;
		}
		++fileCount;
	}
	@endcode

	@note When @ref fplDirectoryListBegin() or @ref fplDirectoryListNext() does not find any match, the internal resources are released automatically.
	@warning If you manually stop the iteration, please call @ref fplDirectoryListEnd() to release its internal resources - otherwise you may leak memory!

	@subsection subsection_category_io_paths_traversing_traversefiles Recursively get all files in a directory

	There is no recursion support built-in in FPL, but you can easily make one using @ref fplDirectoryListBegin() .<br>
	Just iterate through the file entries, which are already explained here: @ref subsection_category_io_paths_traversing_findfiles <br>
	You can check @ref fplFileEntry.type ,to check for either a @ref fplFileEntryType_Directory or a @ref fplFileEntryType_File type to start a recursion or not.<br>

	<b>Example:</b>
	@code{.c}

	// Some existing awesome file-list container api
	typedef struct file_list_t {
		size_t capacity;
		size_t count;
		char **items;
	} file_list_t;
	void init_file_list(file_list_t *outList);
	void free_file_list(file_list_t *outList);
	void push_file_list_item(file_list_t *outList, const char *item);

	static void GetFilesFromDirectory(const char *rootPath, const bool recursive, file_list_t *outList) {
		fplEntry entry;
		for(bool hasEntry = fplDirectoryListBegin(rootPath, "*", &entry); hasEntry; hasEntry = fplDirectoryListNext(&entry)) {
			char path[FPL_MAX_PATH_LENGTH];
			fplPathCombine(path, fplArrayCount(path), 2, rootPath, entry.name);
			if (entry.type == fplFileEntryType_Directory && recursive) {
				GetFilesFromDirectory(path, true, outList);
			} else if (entry.type == fplFileEntryType_File) {
				push_file_list_item(outList, path);
			}
		}
		return(result);
	}

	int main(int argc, char **argv) {
		if (argc < 2) {
			return 1; 
		}
		const char *rootPath = argv[1];
		file_list_t outFileList;
		init_file_list(&outFileList);
		GetFilesFromDirectory(rootPath, true, &outFileList);
		// ... do someting with out file list
		free_file_list(&outFileList);
		return 0;

	@page page_category_threading_threads Threads
	@tableofcontents

	@section section_category_threading_threads_overview Overview
	In this section, you will learn the Basics about creating and handling of Threads.<br>
	With Threads, you can run multiple pieces of code in parallel.<br>
	Threads require the use of @subpage page_category_threading_sync to prevent race conditions.

	@section section_category_threading_threads_create Creating a Thread
	Call @ref fplThreadCreate() with a pointer to @ref fpl_run_thread_callback "callback" and a user pointer argument, to create and immediately run a Thread.<br>

    @code{.c}
    void MyThreadProc(const fplThreadHandle *context, void *data) {
        // ... do something here
    }
    void RunMyThread() {
        int myData = 42;
        fplThreadHandle *thread = fplThreadCreate(MyThreadProc, &myData);
        fplThreadWaitForOne(thread, FPL_TIMEOUT_INFINITE);
    }
    @endcode

	@note The internal Thread resources will be cleaned up automatically after your code has finished running.<br>
	@warning When a Thread has finished running, you cannot use the same @ref fplThreadHandle anymore -> It may be reassigned to another Thread in the future.<br>

	@section section_category_threading_threads_destroy Destroying a Thread?
	You don't have to manually release the Thread resources, this will be cleaned up automatically when either the Thread ends naturally or when it was terminated forcefully using @ref fplThreadTerminate() .
	<br>
	@warning Do not call @ref fplThreadTerminate() to stop or release a Thread! Let the thread exit naturally.

	@section section_category_threading_threads_wait Waiting/Joining for Threads to Exit

	@subsection subsection_category_threading_threads_wait_single Wait for a single Thread to Exit
	Call @ref fplThreadWaitForOne() with a pointer to @ref fplThreadHandle and a @ref fplTimeoutValue argument, to wait for a single Thread to finish.

	@code{.c}
	// Wait until the thread is finished
	fplThreadWaitForOne(thread, FPL_TIMEOUT_INFINITE);

	// ... or

	// Wait at max for 5 seconds to finish the thread
	fplThreadWaitForOne(thread, 5000);
    @endcode

	@subsection subsection_category_threading_threads_wait_any Wait for any Thread to Exit
	Call @ref fplThreadWaitForAny() to wait until at least for one Thread to finish.

	Example, default thread handle array:<br>
	@code{.c}
	fplThreadHandle **threads; // Thread handle array already initialized

	// Wait until one of the threads is finished
	fplThreadWaitForAny(threads, numOfThreads, sizeof(fplThreadHandle *), FPL_TIMEOUT_INFINITE);

	// ... or

	// Wait at max for 5 seconds to finish at least one of the threads -> default stride
	fplThreadWaitForAny(threads, numOfThreads, sizeof(fplThreadHandle *), 5000);
    @endcode

	Example, custom struct with stored thread handle:
	@code{.c}
	typedef struct MyCustomStruct {
		int a;
		void *ptr;
		fplThreadHandle *thread;
		short b;
	} MyCustomStruct;

	MyCustomStruct *customThreads; // Struct array already initialized

	fplThreadHandle **firstPointerToThread = &customThreads[0].thread;

	// Wait until one of the threads is finished
	fplThreadWaitForAny(firstPointerToThread, numOfThreads, sizeof(MyCustomStruct), FPL_TIMEOUT_INFINITE);

	// ... or

	// Wait at max for 5 seconds to finish at least one of the threads -> default stride
	fplThreadWaitForAny(firstPointerToThread, numOfThreads, sizeof(MyCustomStruct), 5000);
    @endcode

	@subsection subsection_category_threading_threads_wait_all Wait for all Threads to Exit
	Call @ref fplThreadWaitForAll() to wait for all Threads to be finished.

	Example, default thread handle array:<br>
	@code{.c}
	fplThreadHandle **threads; // Thread handle array already initialized

	// Wait until all of the threads are finished
	fplThreadWaitForAll(threads, numOfThreads, sizeof(fplThreadHandle *), FPL_TIMEOUT_INFINITE);

	// ... or

	// Wait at max for 5 seconds to finish all threads
	fplThreadWaitForAll(threads, numOfThreads, sizeof(fplThreadHandle *), 5000);
    @endcode

	Example, custom struct with stored thread handle:
	@code{.c}
	typedef struct MyCustomStruct {
		int a;
		void *ptr;
		fplThreadHandle *thread;
		short b;
	} MyCustomStruct;

	MyCustomStruct *customThreads; // Struct array already initialized

	fplThreadHandle **firstPointerToThread = &customThreads[0].thread;

	// Wait until all of the threads are finished
	fplThreadWaitForAll(threads, numOfThreads, sizeof(MyCustomStruct), FPL_TIMEOUT_INFINITE);

	// ... or

	// Wait at max for 5 seconds to finish all threads
	fplThreadWaitForAll(threads, numOfThreads, sizeof(MyCustomStruct), 5000);
    @endcode

	@section section_category_threading_threads_terminate Terminate a thread
	Call @ref fplThreadTerminate() with a pointer to @ref fplThreadHandle as an argument, to forcefully terminate a thread.
	@note Using this will almost immediately terminate the thread and releases its resources.
	@note It is safe to call this when a thread is already terminated.

	@section section_category_threading_threads_states Query the Thread State
	Call @ref fplGetThreadState() with a pointer to @ref fplThreadHandle as an argument, to query the current state.<br>
	If a thread is stopped or in the process of getting stopped, it will return @ref fplThreadState_Stopped or @ref fplThreadState_Stopping respectively.<br>
	If a thread is started or in the process of getting started, it will return @ref fplThreadState_Running or @ref fplThreadState_Starting respectively.<br>

	@section section_category_threading_threads_notes Notes
	@note Your code should always ensure that it will exit eventually. You can use @subpage page_category_threading_sync to achieve this.<br>
	@note It is bad practice to "Terminate" a thread, you should design your code to let threads end naturally.

	@page page_category_threading_mutexes Mutexes
	@tableofcontents

	@section section_category_threading_mutexes_overview Overview
	This section explains how to create and handling of Mutexes.<br>
	A mutex is a Kernel-Level object used to prevent race conditions when multiple Threads access the same code section.<br>
	With a Mutex, you can ensure that only one thread at a time can access a code section.

	@section section_category_threading_mutexes_init Initialize a Mutex
	Call @ref fplMutexInit() with a pointer to @ref fplMutexHandle argument, to initialize a Mutex.<br>
	After the initialization is done, you can start locking and unlocking it.<br>
	When you are done with the Mutex call @ref fplMutexDestroy() to release its internal resources.

	@code{.c}
	fplMutexHandle mutex;
	if (!fplMutexInit(&mutex)) {
	    // Error: Mutex failed initializing -> Too many active mutexes for this process or already initialized
	}

	// ... Mutex is not required anymore
	fplMutexDestroy(&mutex);
    @endcode

	@section section_category_threading_mutexes_locking Locking/Unlocking a Mutex

	@subsection subsection_category_threading_mutexes_locking_lock Locking a Mutex
	Call @ref fplMutexLock() with a pointer to @ref fplMutexHandle as an argument, to lock a Mutex.<br>
	It this Mutex is already locked, the current thread will wait forever until it gets unlocked by the owner Thread.<br>
	If this Mutex is not locked yet, it will be locked by the calling Thread.<br>

	@note You should always unlock the @ref fplMutexHandle as soon as possible - on the same call stack.<br>

	@subsection subsection_category_threading_mutexes_locking_unlock Unlocking a Mutex
	Call @ref fplMutexUnlock() with a pointer to @ref fplMutexHandle as an argument, to unlock a Mutex.<br>
	The Mutex will be unlocked only when this function is called from the owner Thread.<br>
	If this Mutex was not locked or the owner Thread does not match it will fail.

	@subsection subsection_category_threading_mutexes_locking_probe Trying to lock a Mutex
	Call @ref fplMutexTryLock() with a pointer to @ref fplMutexHandle as an argument, to try to lock a Mutex.<br>
	If the Mutex is already locked, the current thread will not be blocked and the function returns false.<br>
	If this Mutex is not locked yet, it will be locked by the calling Thread.<br>

    @subsection subsection_category_threading_mutexes_locking_example Example

	@code{.c}
	// Lock down the execution of a code section to one Thread at a time
	fplMutexLock(&mutex);
	{
	    // Do something in this critical section here
	}
	fplMutexUnlock(&mutex);

	// Locking a mutex can fail, so ensure that you check the result

	This section explains how to create and manage Signals.<br>
	A Signal is a Kernel-Level object used to notify one or multiple waiting Threads.<br>
	It internally contains a Value which is either @ref fplSignalValue_Set or @ref fplSignalValue_Unset.<br>
	When this value gets changed, all Threads which waits on that Signal will wakeup.<br>
	They can be shared across process boundaries and may be used as standalone locks to shared data, but the number of Signals is limited by the OS that can be allocated at a time.

	@section section_category_threading_signals_init Initialize a Signal
	Call @ref fplSignalInit() with a pointer to @ref fplSignalHandle as an argument, to initialize a Signal.<br>
	Also, you need to specify if the Signal starts as @ref fplSignalValue_Set or @ref fplSignalValue_Unset as a second argument.<br>

	@section category_threading_conditions_signal Send a Signal to a Condition-Variable to one waiting Thread
	Call @ref fplConditionSignal() with a pointer to @ref fplConditionVariable, to signal any waiting Threads.<br>
	If you want to let multiple Threads waits on the same Condition-Variable, use @ref fplConditionBroadcast() instead.<br>
	@note Unlike Signals Condition-Variables does not need a Mutex for signaling.

	@section section_category_threading_semaphores_overview Overview
	This section explains how to create and manage semaphores.<br>
	Semaphores are similar to @subpage page_category_threading_mutexes "Mutexes" but have one major difference: Any Thread can release it!<br>
	It internally uses an atomic counter which gets incremented and decremented.

	@section category_threading_semaphores_init Initialize a Semaphore
	Call @ref fplSemaphoreInit() to initialize a Semaphore with a @ref fplSemaphoreHandle as an argument. Also, you need to specify the initial value for the Semaphore to start with.<br>
	Call @ref fplSemaphoreDestroy() when you are done with that Semaphore to let it releases its internal resources.

	@code{.c}
	fplSemaphoreHandle semaphore;
	if (!fplSemaphoreInit(&semaphore, 1)) {
	    // Error: Semaphore failed to initialize -> This will most likely never happen
	}

	// ... Semaphore is not required anymore and no threads are waiting on it
	fplSemaphoreDestroy(&semaphore);
    @endcode

	@section category_threading_semaphores_wait Waiting/Locking a Semaphore
	Call @ref fplSemaphoreWait() to let a Thread wait and decrement the Semaphores value with a @ref fplSemaphoreHandle as an argument.<br>
	If the Semaphores value is greater than zero, then the decrement will happen and the function returns immediately.<br>
	If the Semaphores value is zero then the Thread will wait until it is possible to decrement the value.<br>
	Also, you need to specify the number of milliseconds you want the thread to wait. If FPL_TIMEOUT_INFINITE is passed, it will wait forever.<br>

	@code{.c}
	// Wait until the Semaphores value is > 0
	fplSemaphoreWait(&semaphore, FPL_TIMEOUT_INFINITE);

	// ... or

	// Wait at max for 5 seconds to the Semaphores value to be > 0
	fplSemaphoreWait(&semaphore, 5000);
    @endcode

	@section category_threading_semaphores_wait_multiple Waiting on multiple Semaphores?

	@page page_category_threading_atomics Atomics
	@tableofcontents

	@section category_threading_atomics_overview Overview
	This section explains what atomics is and how they are used.<br>
	Since decades CPUs have hardware CPU instructions for doing thread-safe math and compare operations built-in.<br>
	These instructions are available as built-in intrinsics in any modern C/C++ compiler.<br>
	In FPL these are called Atomics and are wrapper functions around those intrinsics.<br>
	<br>
	Atomics functions generate memory barriers (or fences) to ensure that memory operations are completed in order.

	@section category_threading_atomics_add Fetch-And-Add (Add)
	With a Fetch-And-Add instruction, you can do an atomic addition and get the previous value **before** the add back as an atomic operation.<br>

	Pseudo code:
	@code
	oldValue = *storageValue;
	*storageValue = oldValue + inc;
	return oldValue;
	@endcode

	FPL have several versions for that for various datatypes:
	- @ref fplAtomicFetchAndAddU32()
	- @ref fplAtomicFetchAndAddU64()
	- @ref fplAtomicFetchAndAddS32()
	- @ref fplAtomicFetchAndAddS64()
	- @ref fplAtomicFetchAndAddSize()
	- @ref fplAtomicFetchAndAddPtr()

	Usage:
	@code{.c}
	volatile uint32_t storageValue;
	uint32_t oldValue = fplAtomicFetchAndAddU32(&storageValue, 7);
	@endcode

	@section category_threading_atomics_inc Add-And-Fetch (Increment)
	With an Add-And-Fetch instruction, you can do an atomic addition by **one** and get the new value back **after** the increment as an atomic operation.<br>
	
	Pseudo code:
	@code
	*StorageValue++;
	NewValue = *StorageValue;
	return newValue;
	@endcode

	FPL have several versions for that for various datatypes:
	- @ref fplAtomicAddAndFetchU32()
	- @ref fplAtomicAddAndFetchU64()
	- @ref fplAtomicAddAndFetchS32()
	- @ref fplAtomicAddAndFetchS64()
	- @ref fplAtomicAddAndFetchSize()
	- @ref fplAtomicAddAndFetchPtr()

	Usage:
	@code{.c}
	volatile uint32_t storageValue;
	uint32_t newValue = fplAtomicAddAndFetchU32(&storageValue);
	@endcode

	@section category_threading_atomics_exchange Exchange
	With a Exchange instruction, you can do an atomic exchange and get the previous value back **before** the change as an atomic operation.<br>
	
	Pseudo code:
	@code
	oldValue = *storageValue;
	*storageValue = exchangeValue;
	return oldValue;
	@endcode

	FPL have several versions for that for various datatypes:
	- @ref fplAtomicExchangeU32()
	- @ref fplAtomicExchangeU64()
	- @ref fplAtomicExchangeS32()
	- @ref fplAtomicExchangeS64()
	- @ref fplAtomicExchangeSize()
	- @ref fplAtomicExchangePtr()

	Usage:
	@code{.c}
	volatile uint32_t storageValue;
	uint32_t newValue = fplAtomicStoreU32(&storageValue, 1337);
	@endcode

	@note The exchange atomics is identical to @ref category_threading_atomics_store, except that the exchange atomics will return the previous value before the change.

	@section category_threading_atomics_store Store
	With a Store instruction, you can do a memory write as an atomic operation.<br>
	
	Pseudo code:
	@code
	*storageValue = newValue;
	@endcode

	FPL have several versions for that for various datatypes:
	- @ref fplAtomicStoreU32()
	- @ref fplAtomicStoreU64()
	- @ref fplAtomicStoreS32()
	- @ref fplAtomicStoreS64()
	- @ref fplAtomicStoreSize()
	- @ref fplAtomicStorePtr()

	Usage:
	@code{.c}
	volatile uint32_t storageValue;
	fplAtomicStoreU32(&storageValue, 1337);
	@endcode

	@note The store atomics is identical to @ref category_threading_atomics_exchange, except that the store atomics won't return any value.

	@section category_threading_atomics_load Load
	With a Load instruction, you can do a memory read as an atomic operation.<br>
	
	Pseudo code:
	@code
	return *storageValue;
	@endcode

	FPL have several versions for that for various datatypes:
	- @ref fplAtomicLoadU32()
	- @ref fplAtomicLoadU64()
	- @ref fplAtomicLoadS32()
	- @ref fplAtomicLoadS64()
	- @ref fplAtomicLoadSize()
	- @ref fplAtomicLoadPtr()

	Usage:
	@code{.c}
	volatile uint32_t storageValue;
	uint32_t value = fplAtomicLoadU32(&storageValue);
	@endcode

	@section category_threading_atomics_cas Compare-And-Swap
	With a Compare-And-Swap instruction, you can check a value against another and exchange them as an atomic operation.<br>
	The previous/current value will always be returned regardless of the result.<br>

	Pseudo code:
	@code
	oldValue = *storageValue;
	if (oldValue == comparend) {
		*storageValue = exchangeValue;
	}
	return oldValue;
	@endcode

	FPL have several versions for that for various datatypes:
	- @ref fplAtomicCompareAndSwapU32()
	- @ref fplAtomicCompareAndSwapU64()
	- @ref fplAtomicCompareAndSwapS32()
	- @ref fplAtomicCompareAndSwapS64()
	- @ref fplAtomicCompareAndSwapSize()

	- @ref fplAtomicIsCompareAndSwapS64()
	- @ref fplAtomicIsCompareAndSwapSize()
	- @ref fplAtomicIsCompareAndSwapPtr()

	Usage:
	@code{.c}
	volatile uint32_t storageValue = 0;
	uint32_t oldValue = fplAtomicCompareAndSwapU32(&storageValue, 0, 1337);
	// The first thread executing this will see 0 as the oldValue, all others will see 1337

	// or
	volatile uint32_t storageValue = 0;
	if (fplAtomicIsCompareAndSwapU32(&storageValue, 0, 1337)) {
		// The first thread executing this to 1337 will get here
	} else {
		// All other threads gets here
	}
	@endcode

	@section section_category_threading_atomics_barriers Memory Barriers
	With memory barriers you can prevent the compiler from reordering memory reads/writes.<br>
	In FPL additional CPU fences may be added to ensure that the previous memory operations are completed before the future ones.<br>
	
	@subsection subsection_category_threading_atomics_barriers_without Without fences

	@code{.c}
	int theValue;
	int valueIsPublished = 0;
	void updateValue(int newValue) {
		// The compiler may move the write above the the value set
		theValue = newValue;
		valueIsPublished = 1;
	}

	int getValue() {
		// The compiler may move the read of value before the publish check
		if (valueIsPublished) {
			return theValue;
		}
		return -1;
	}
	@endcode

	@warning This example may break even on a single-threaded environment!

	@subsection subsection_category_threading_atomics_barriers_full With a read/write barrier

	@code{.c}
	int theValue;
	int valueIsPublished = 0;
	void updateValue(int newValue) {
		theValue = newValue;
		// The value is written before the publish is set
		fplAtomicReadWriteFence();
		valueIsPublished = 1;
	}

	int getValue() {
		// The publish is read before the value is being returned
		if (valueIsPublished) {
			fplAtomicReadWriteFence();
			return theValue;
		}
		return -1;
	}
	@endcode

	@subsection subsection_category_threading_atomics_barriers_read_or_write Read or Write
	In some special cases you don't have to issue a full memory barrier like @ref fplAtomicReadWriteFence(), so you can just use a read or write barrier only:<br>
	- You can use @ref fplAtomicReadFence() to just ensure memory writes are completed before future ones only (Plus preventing from compiler reordering memory writes).<br>
	- You can use @ref fplAtomicWriteFence() to just ensure memory reads are completed before future ones only (Plus preventing from compiler reordering memory reads).<br>

	@subsection subsection_category_threading_atomics_barriers_atomics Atomics vs Barriers?

	Atomic functions may include memory barriers to ensure that CPU memory read/write instructions are executed in order and to prevent the compiler from reordering memory read/writes.<br>
	This means you don't have to use any kind of memory barriers around atomic functions ;-)

	@page page_faq FAQ
	@tableofcontents

	@section section_faq FAQ

	@subsection subsection_faq_license What are the license requirements for FPL?
	Final Platform Layer is released under the @subpage page_license "MIT License".<br>
	This license allows you to use FPL freely in any software.<br>

	@subsection subsection_faq_costs I did pay for FPL, did I get ripped-of?
	Yes, you are! FPL is fully open source and costs nothing.

	@subsection subsection_faq_inwhatlanguage In what language is FPL written?
	Final Platform Layer is written in C99 for simplicity and best portability, but is C++/11 compatible as well.<br>
	It uses standard types such as uint32_t or intptr_t from <stdint.h> <stddef.h> and <stdbool.h> to ensure correctness on all platforms.<br>
	For certain features such as printf(), getchar() the CRT (C-Runtime-Library) are used, but you can disable it if needed.<br>

	@subsection subsection_faq_whyshouldiuse What makes it different from other platform abstraction libraries, such as SDL/SFML, etc. ?
	- FPL is designed to require bare minimum linking to the OS (kernel32.lib / libld.so) only.
	- It does not require any dependencies or build-systems to get it running.
	- It has a lightweight feature set.
	- No data hiding -> everything is accessible.
	- It uses a fixed and small memory footprint and handles memory very gracefully.
	- FPL can be controlled by configuration in very detail at startup.
	- You decide how to integrate it; not the library. You can statically link it, you can dynamically link it, or you can just include the full source.

	@subsection subsection_faq_whyisfplsobig Why is FPL so big?
	Final Platform Layer contains headers and implementations for all supported platforms with all the function prototypes for linking operating system functions dynamically.<br>
	Also the entire API definition is documented inline and it comes with a full detailed changelog.<br>

	@subsection subsection_faq_howdoesitwork How does it work?
	FPL relies heavy on preprocessor defines, used for detecting the current architecture / compiler / operating system.<br>
	This makes it possible to enable/disable certain code-paths for certain platform/compiler combinations.<br>
	Only built-in OS operating system functions are used in every situation and the usage of standard library functions is prevented by all means.<br>
	<br>
	To prevent code duplication, FPL implements either platform sets or just subsets which can be used for other platforms
	For example, Linux is a POSIX-based platform so it uses POSIX libraries, such as pthread / X11, etc.
	The pthread and X11 implementation are separated, so other Unix-based platforms can use that implementation without any problem.
	<br>
	On top of that FPL implements multiple audio and video backends, so that all platforms can playback audio and render using a supported graphics API.<br>

	@subsection subsection_faq_limitations Does FPL have some limitations?
	Yes, it does have some limitations, because it cannot do everything for you:
	- No audio DSP is going on, so you have to convert the samples into the proper format (Sample rate, Channels, Format type) FPL expects.
	- There are no rendering functions included, except for presenting the current frame. So you have to load and call the correct API functions yourself.
	- FPL has a lightweight feature set, so it may not have all the features you may need.

	@subsection subsection_faq_strings How does FPL handle strings?
	On every platform, all strings/paths are expected to be UTF-8 always!<br>
	If you need to convert Unicode/UTF-16 based strings there are conversion functions built-in.

	@subsection subsection_faq_thirdparty_libs Can FPL handle third-party libraries?
	Yes it works very well with other libraries. There are several demo projects in the repository which show that.<br>
	<br>
	Here is a short list of tested third-party libraries with FPL:

	- C-Standard Library
	- C++ Standard Template Library
	- STB Libraries
	- Glew/Glad
	- PhysX
	- Box2D
	- GLM
	- ImGUI
	- FFMPEG

	But it won't work with other platform abstraction libraries such as SDL, SFML, GLUT, GLFW, etc.<br>
	All these other platform abstraction libraries have their way of providing the main entry point and may not compatibility with each other.

	@page page_nocrt How to disable the use of the CRT in FPL
	@tableofcontents

	@section section_nocrt_consequences Consequences of disabling the CRT

	If you disable the CRT, you lose a lot of functionality which we today take for granted:<br>

	- No functions from the entire C standard library stack, such as "stdio.h" / "stdlib", / "math.h" / "string.h", etc.
	- No or limited integer mul/div operations on some platforms
	- No console input/output
	- No C++ exceptions
	- Limited security checks
	- No automatic entry point mapping to main() or WinMain()
	- Limited floating point operations on some platforms
	- Limited stack size

	Some limitations can be corrected by setting up the compiler properly, such as stack size, security checks, etc.<br>
	<br>
	So if you are fine with that, the next section describes how to do disable the CRT usage in FPL.

	@section section_nocrt_requirements Requirements for disabling the CRT in FPL

	- You have read the @ref section_nocrt_consequences
	- You know what you are doing
	- You already disabled the CRT by compiler settings
	- You fixed the security checks and stack size by compiler settings

	@section bsection_nocrt_disableit Disable the CRT in FPL

	To disable the use of the C-Runtime Library, you need to set certain preprocessor definitions:

	- Define **FPL_NO_CRT** in all translation units where FPL implementation is included
	- In your main translation-unit, you need to define the application type **FPL_APPTYPE_CONSOLE** or **FPL_APPTYPE_WINDOW** explicitly

	@code{.c}
	#define FPL_NO_CRT // Disable CRT support in FPL
	#define FPL_APPTYPE_CONSOLE // or FPL_APPTYPE_WINDOW
	#define FPL_IMPLEMENTATION // FPL_NO_CRT must be set set in the implementation only
	#include <final_platform_layer.h>
	@endcode

	@section section_nocrt_provfunccrt Providing intrinsics (Mini-CRT)

	Some compilers such as MSVC require certain stuff to compile properly.<br>
	You are responsible to provide that stuff if you get compile errors.<br>
	<br>
	A few errors you may get:

	Runtime check:
	- unresolved external symbol __RTC_Shutdown
	- unresolved external symbol __RTC_InitBase
	- unresolved external symbol __RTC_CheckEsp
	- unresolved external symbol __RTC_CheckStackVars

	Float:
	- unresolved external symbol __fltused -> Global used in MSVC
	- unresolved external symbol __ltod3 -> Double division intrinsic

	Integer:
	- unresolved external symbol __allmul -> Long-Long integer multiplication intrinsic

	Other:
	- unresolved external symbol __memset -> memset intrinsic (May use fplMemorySet)
	- unresolved external symbol __memcpy -> memcpy intrinsic (May use fplMemoryCopy)

	To solve those compile errors it is recommended to use a mini-crt library or write all the functions yourself.<br>

	@section section_nocrt_notes Notes

	Right now FPL has No-CRT support for Win32 only! If you need this for other platforms let me know.

	@section section_compiler_options_detection Platform/Compiler detection

	Like every other C/C++ program, FPL uses compiler defines to detect the proper platform/architecture and used compiler.<br>
	If you need this information for whatever reason you can simply compare the defines:

	- **FPL_PLATFORM_WIN32** or **FPL_PLATFORM_LINUX** or **FPL_PLATFORM_UNIX** ...
	- **FPL_ARCH_X64** or **FPL_ARCH_X86** or **FPL_ARCH_ARM64* ...

	All these defines have no values set, there are just "defined" - use always defined() for checking them.

	@code{.c}
	#if defined(FPL_PLATFORM_WINDOWS)
		// ... Any win32 code you may need
	#endif // FPL_PLATFORM_WIN32

	#if defined(FPL_ARCH_X64)
		// ... Any x64 code you may need
	#endif // FPL_ARCH_X64

	#if defined(FPL_COMPILER_MSVC)
		// ... MSVC compiler specific code you may need
	#endif // FPL_COMPILER_MSVC
	@endcode

	@section section_compiler_options_subplatform Sub-Platforms

	To prevent code duplication for platform combinations, FPL uses sub-platforms - which are no real platforms, but rather principles or standards the actual operating system is built-on.<br>
	For example "Linux" is detected as **FPL_PLATFORM_LINUX** but uses POSIX as a sub-platform **FPL_SUBPLATFORM_POSIX**.<br>
	Another example is "FreeBSD" which is a UNIX-based operation system that uses POSIX standards as well, so it uses the same POSIX sub-platform.<br>
