NAME

       io_eagain - tell io_wait that you got an EAGAIN

SYNTAX

       #include <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.
