Such a function does not exist in my installation.Also, no, it does not document itself.There's no reason to make a function that actually does nothing. It just takes up space. So either the person had no idea what they're doing, or it does do something (potential example: making an object specific to that add-on halt [do nothing] for a period of time) albeit with a bad name
No, it literally does nothing (at least by itself), and I did have a reason for making it.
Mind elaborating on that reason?
Schedules.
