Syntax
Description

SYNTAX

#include <io.h>

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

DESCRIPTION

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

[bu] io_tryread returns -1 (the descriptor is not ready for reading), and
[bu] the descriptor has a timeout, and
[bu] the read attempt was after the descriptor’s timeout,

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