Just a quick question.. Is there any difference to using
a void or function other than void is pure mode and function
is legacy mode. eg: Do they execute in a different way.
Is one more flexable than the other.

Please explain...

Hello,

a function returns a var while a void doesn't return anything.

Ah ok, Thanks for the quick reply..

So basicly, If I don't need a return value I can just use void?

Yes, exactly.
Unless you want to return a pointer of unspecified type - in that case you would use a void* rather than a void.
