Oops. One other thing I forgot. You wouldn't want to return a "void *"
if you're planning on casting that to a function pointer. Pointers to
void are not compatible with pointers to functions. You at least need
it to return a generic function pointer of some sort. Perhaps something
like: "typedef void (*(*state)())()". I.e., state is a pointer to a 
function that returns a vanilla function pointer. ("Vanilla function
pointer" means "pointer to function of unspecified arguments that
returns nothing", but this is irrelevant since it will be cast to the
proper function pointer type before invoking.)
