eio_custom - Execute custom request like any other eio_*call.

SYNOPSIS

       resource eio_custom (callable  $execute, int  $pri, callable  $callback, [mixed	$data = NULL])

DESCRIPTION

       eio_custom(3) executes custom function specified by $execute processing it just like any other eio_* call.

PARAMETERS

	      o $execute
		- Specifies the request function that should match the following prototype:

	      mixed execute(mixed data);

	      void callback(mixed data, mixed result);

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

EXAMPLES

       Example #1

	      eio_custom(3) example

	      <?php
	      /* Callback for the custom callback */
	      function my_custom_callback($data, $result) {
		  var_dump($data);
		  var_dump(count($result));
		  var_dump($result['data_modified']);
		  var_dump($result['result']);
	      }

	      /* The custom request */
	      function my_custom($data) {
		  var_dump($data);

		  $result  = array(
		      'result'	      => 1001,
		      'data_modified' => "my custom data",
		  );

		  return $result;
	      }

	      $data = "my_custom_data";
	      $req = eio_custom("my_custom", EIO_PRI_DEFAULT, "my_custom_callback", $data);
	      var_dump($req);
	      eio_event_loop();
	      ?>

	      The above example will output something similar to:

	      resource(4) of type (EIO Request Descriptor)
	      string(14) "my_custom_data"
	      string(14) "my_custom_data"
	      int(2)
	      string(14) "my custom data"
	      int(1001)

PARAMETERS

		- Path for the new directory.

	      o $mode
		- Access mode, e.g. 0755

	      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.

EXAMPLES

       Example #1

	      eio_mkdir(3) example

	      <?php
	      $temp_dirname = "eio-temp-dir";

	      /* Is called when eio_mkdir() finishes */
	      function my_mkdir_callback($data, $result) {
	       if ($result == 0 && is_dir($temp_dirname)
		 && !is_readable($temp_dirname)
		 && is_writable($temp_dirname)) {
		echo "eio_mkdir_ok";
	       }

	       // Remove directory
		  if (file_exists($data))
		      rmdir($temp_dirname);
	      }

	      // Create directory with access mode 0300
