Description

io_trywritetimeout - write to a descriptor without blocking

#include <libowfat/io.h>

int io_trywritetimeout(int64 fd,const char* buf,int64 len);

io_trywritetimeout is identical to io_trywrite, with the following exception: if

	•		io_trywrite returns -1 (the descriptor is not ready for writing), and
	•		the descriptor has a timeout, and
	•		the write attempt was after the descriptor’s timeout,

then io_trywritetimeout instead returns -2, with errno set to ETIMEDOUT.
