Display File upload quota on dashboard. It is hooked to the 'activity_box_end' action hook, and in multisite installs, displays the file upload quota at the bottom of the activity dashboard widget.
<?php wp_dashboard_quota(); ?>
This function does not except any parameters.
Counter-intuitively, this function returns true if the conditions to display the quota are not met. There is no return otherwise.
