= dirname(__FILE__)."/eio-temp-file.dat";
touch($filename);
$new_filename = dirname(__FILE__)."/eio-temp-file-new.dat";

function
my_rename_cb($data, $result) {
global
$filename, $new_filename;

if (
$result == 0 && !file_exists($filename) && file_exists($new_filename)) {
@
unlink($new_filename);
echo
"eio_rename_ok";
} else {
@
unlink($filename);
}
}

eio_rename($filename, $new_filename, EIO_PRI_DEFAULT, "my_rename_cb", $filename);
eio_event_loop();
