.TH io_trywritetimeout 3
.SH NAME
io_trywritetimeout \- write to a descriptor without blocking
.SH SYNTAX
.B #include <libowfat/io.h>
int \fBio_trywritetimeout\fP(int64 fd,const char* buf,int64 len);
.SH DESCRIPTION
io_trywritetimeout is identical to io_trywrite, with the following
exception: if
.RS 0
.IP \[bu] 3
io_trywrite returns -1 (the descriptor is not ready for writing), and
.IP \[bu]
the descriptor has a timeout, and
.IP \[bu]
the write attempt was after the descriptor's timeout,
.RE
then io_trywritetimeout instead returns -2, with errno set to ETIMEDOUT.
