eio_cancel() example

<?php
 /* Is called when eio_nop() finished */
 function my_nop_cb($data, $result) {
  echo "my_nop ", $data, "\n";
 }
 
// This eio_nop() call will be cancelled
$req = eio_nop(EIO_PRI_DEFAULT, "my_nop_cb", "1");
var_dump($req);
eio_cancel($req);
 
// This time eio_nop() will be processed
eio_nop(EIO_PRI_DEFAULT, "my_nop_cb", "2");
 
// Process requests
eio_event_loop();
?>

The above example will output something similar to:

resource(4) of type (EIO Request Descriptor)
my_nop 2
