event_add - Add an event to the set of monitored events

SYNOPSIS

       bool event_add (resource  $event, [int  $timeout = -1])

DESCRIPTION

       event_add(3) schedules the execution of the $event when the event specified in event_set(3) occurs or in at least the time specified by the
       $timeout argument. If $timeout was not specified, not  timeout  is  set.  The  $event  must  be	already  initalized  by  event_set(3)  and
       event_base_set(3) functions. If the $event already has a timeout set, it is replaced by the new one.

PARAMETERS

	      o $event
		- Valid event resource.

	      o $timeout
		- Optional timeout (in microseconds).

RETURN VALUES

       event_add(3) returns TRUE on success or FALSE on error.

eio_get_event_stream - Get stream representing a variable used in internal communications with libeio.

SYNOPSIS

       mixed eio_get_event_stream (void  )

DESCRIPTION

       eio_get_event_stream(3)	acquires  stream  representing	a variable used in internal communications with libeio. Could be used to bind with
       some event loop provided by other PECL extension, for example libevent.

PARAMETERS

       This function has no parameters.

RETURN VALUES

       eio_get_event_stream(3) returns stream on success; otherwise, NULL

EXAMPLES

       Example #1

	      Using eio with libevent

	      <?php
	      function my_eio_poll($fd, $events, $arg) {
		  /* Some libevent regulation might go here .. */
		  if (eio_nreqs()) {
		      eio_poll();
		  }
		  /* .. and here */
	      }

	      function my_res_cb($d, $r) {
		  var_dump($r); var_dump($d);
	      }

	      $base = event_base_new();
	      $event = event_new();

	      $fd = eio_get_event_stream();
	      var_dump($fd);

	      eio_nop(EIO_PRI_DEFAULT, "my_res_cb", "nop data");
	      eio_mkdir("/tmp/abc-eio-temp", 0750, EIO_PRI_DEFAULT, "my_res_cb", "mkdir data");
	      /* some other eio_* calls here ... */

	      // set event flags
	      event_set($event, $fd, EV_READ /*| EV_PERSIST*/, "my_eio_poll", array($event, $base));

	      // set event base
	      event_base_set($event, $base);

	      // enable event
	      event_add($event);

	      // start event loop
	      event_base_loop($base);

	      /* The same will be available via buffered libevent interface */
	      ?>

	      The above example will output something similar to:

	      int(3)
	      int(0)
	      string(8) "nop data"
	      int(0)
	      string(10) "mkdir data"
