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, and some	thread
       is calling iom_wait at the time,	it 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_wait again 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_wait, iom_abort
