io_eagain(3)		   Library Functions Manual		  io_eagain(3)

NAME
       io_eagain - tell	io_wait	that you got an	EAGAIN

SYNTAX
       #include	<libowfat/io.h>

       void io_eagain(int64 fd);

DESCRIPTION
       If  io_wait() said that you can read from a descriptor, you try to read
       from it,	and you	get EAGAIN, you	need to	tell io_wait().	 This  is  im-
       portant	for edge triggered event notification schemes like Linux 2.4's
       SIGIO, or you will lose events.

       io_tryread(), io_trywrite() and io_sendfile()  and  iob_send()  already
       take care of this for you.

       This  function  is  only	 of  interest  if you integrate	io_wait() with
       legacy code that	uses read/write	directly.
