iom_add(3)		   Library Functions Manual		    iom_add(3)

NAME
       iom_add - add event to I/O multiplexer

SYNTAX
       #include	<libowfat/io.h>

       int iom_add(iomux_t* c, int64 fd, unsigned int events);

DESCRIPTION
       iom_add adds an event you are interested	in to an I/O multiplexer.

       fd is the file descriptor (usually a socket) you	are interested in, and
       events  is  the	operation  you	want  to  do.  It  can	be IOM_READ or
       IOM_WRITE.

       If that operation becomes possible on that  descriptor,	iom_wait  will
       return and tell you the fd and the event.

       Note that the event registration	is removed from	the iomux_t context if
       it  occurs.  You	 will  have  to	call iom_requeue after you handled the
       event, if you are still interested in it.

       Closing a file descriptor with registered events	will discard the event
       registration.

LINKING
       You may have to add -lpthread to	the command line in the	linking	step.

RETURN VALUE
       iom_add returns 0 on success and	-1 on error, setting errno.

SEE ALSO
       iom_init, iom_requeue, iom_wait,	iom_abort
