man io_trywritetimeout () - write to a descriptor without blocking

NAME

io_trywritetimeout - write to a descriptor without blocking

SYNTAX

#include <io.h>

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

DESCRIPTION

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

[bu]
io_trywrite returns -1 (the descriptor is not ready for writing), and
[bu]
the descriptor has a timeout, and
[bu]
the write attempt was after the descriptor's timeout,

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