What does Void do?


Recommended Posts

Regardless of the language (I suppose you're talking about ActionScript), "void" is "nothing". That is, when you say a function doesn't accept any parameter, you say "functionName( void )" in it's declaration to show that. Look at how some PHP functions are declared for example."void" is different than "null" in that "null" is a value that means nothing, and "void" means there isn't any value, including a value that means nothing.
