	      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

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)
