I am running a local development Drupal site on a Windows machine. I am trying to use the dd($data, $label = NULL) function from the devel module to help debug. Using this function, should write debug info to a drupal_debug.txt file in the /tmp folder on the machine where the Drupal site is hosted.

On my Windows machine, although I am using this function, the drupal_debug.txt file is not getting created anywhere, leading me to believe I am using the function incorrectly.

Here is a snippet of how I am using it,

<?php
$test = "this is my test";
dd($test, $label = NULL);

I am looking for an example of the correct syntax for the dd($data, $label = NULL) function. I have the Devel module enabled.
