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 important 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.
