 Gets the next argument from sfall. Each time it's called it returns the next argument, or otherwise it returns 0 if there are no more arguments left.

 > void register_hook(int hooktype)
 Used from a normal global script if you want to run it at the same point a full hook script would normally run. In case of this function, "start" proc will be executed in a current global script. You can use all above functions like normal.
