NAME

       io_tryreadtimeout - read from a descriptor without blocking

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

       •  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.
