EIO_GET_EVENT_STREAM(3) 						 1						   EIO_GET_EVENT_STREAM(3)

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"

eio_lstat - Get file status

SYNOPSIS

       resource eio_lstat (string  $path, int  $pri, callable  $callback, [mixed  $data = NULL])

DESCRIPTION

       eio_lstat(3) returns file status information in $result argument of $callback

PARAMETERS

	      o $path
		- The file path

	      o $pri
		-The  request  priority:  EIO_PRI_DEFAULT,  EIO_PRI_MIN,  EIO_PRI_MAX,	or  NULL.  If  NULL  passed,  $pri  internally	is  set to
		EIO_PRI_DEFAULT.

	      o $callback
		-$callback function is called when the request is done. It should match the following prototype:

	      void callback(mixed $data, int $result[, resource $req]);

		     o $data
		       -is custom data passed to the request.

		     o $result
		       -request-specific result value; basically, the value returned by corresponding system call.

		     o $req
		       -is optional request resource which can be used with functions like eio_get_last_error(3)

	      o $data
		- Arbitrary variable passed to $callback.

RETURN VALUES

       eio_lstat(3) returns request resource on success or FALSE on error.

EXAMPLES

       Example #1

	      eio_lstat(3) example

	      <?php
	      $tmp_filename = dirname(__FILE__). "/eio-file.tmp";
	      touch($tmp_filename);

	      function my_res_cb($data, $result) {
		  var_dump($data);
		  var_dump($result);
	      }

	      function my_open_cb($data, $result) {
		  eio_close($result);
		  eio_event_loop();

		  @unlink($data);
	      }

	      eio_lstat($tmp_filename, EIO_PRI_DEFAULT, "my_res_cb", "eio_lstat");
	      eio_open($tmp_filename, EIO_O_RDONLY, NULL,
	       EIO_PRI_DEFAULT, "my_open_cb", $tmp_filename);
	      eio_event_loop();
	      ?>

	      The above example will output something similar to:

	      string(9) "eio_lstat"
	      array(12) {
	       ["st_dev"]=>
		int(2050)
