List of functions a function calls

[Miiru]

Is it possible to get a list of functions a function calls? Or to output them ingame?

I am looking at this function: http://wowprogramming.com/docs/api/UseToy

They seem to have changed something on ptr and it would probably be helpful for me to know which functions it calls. Didnt find anything related in blizzard_collections addons.

Thanks
