io_trywritetimeout(3)                       DragonFly Library Functions Manual

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

       o  io_trywrite returns -1 (the descriptor is not ready for writing),
          and

       o  the descriptor has a timeout, and

       o  the write attempt was after the descriptor's timeout,

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