io_tryreadtimeout(3)

NAME
io_tryreadtimeout - read from a descriptor without blocking

SYNTAX
#include <libowfat/io.h>

int io_tryreadtimeout(int64 fd,char* buf,int64 len);

DESCRIPTION
io_tryreadtimeout is identical to io_tryread, with the following exception: if

    •   io_tryread returns -1 (the descriptor is not ready for reading), and

    •   the descriptor has a timeout, and

    •   the read attempt was after the descriptor's timeout,

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