openkal reads and writes a file at its position and has no transfer at an offset. The four positional calls answered ENOSYS, which no configure check sees because the functions link; LLVM reads every file through
pread, and clangd built as an ok image could open none (probe Sunrisepeak/mcppls-clangd#11).port/src/okm_syscall.c:do_transfer_atseeks to the offset, transfers, and seeks back, under the descriptor table's lock. A descriptor that is not a file answers ESPIPE.musl/PATCHES.md: the one difference a caller can tell (a plain read in another thread between the two seeks).examples/posix: pread and pwrite at an offset, and the position unchanged.Co-authored-by: speak-agent 248744407+speak-agent@users.noreply.github.com
