in the function declaration you seem to declare your function like:
"void funname(...)"
which means that you do not intend to "return" anything.
then in the function body you do return something of type "(void*)";
this is illegal.

even you replace "void" with "int" (or any other type) this would be
illegal: a pointer to an object is not the same as an object of that type.
with "void" things are a bit more complicated (conceptually, not
practically): "(void)" is synonymous for 'nothing', whereas "(void*)" is
synonymous for 'pointer of undefined type'

most likely you have unmatched pairs with your paranthesis.
use an editor that does paranthesis highlighting and parantheses based
indentation to track this down. (or just read your code carefully ;-))
