[Dev-C++] Passing function address as a parameter.

[Odilon J. B. - U. <ob...@un...>]

Hi !

I'm using DevCpp in games development and I'm having a problem about =
passing function address as a parameter.

Example:

void show_message() {
    printf("Message\n");
}

void call_function(void *func) {
    // I receive the pointer to de function, but I can't execute it, =
like this:
    func();
}

int main() {
    call_function((void*)show_message);
    getch();
}


In order to execute the function passed as parameter, I have this =
option:

void show_message() {
    printf("Message\n");
}

void call_function(void func()) {
    // This works fine, but I can't store the address of func() to =
execute it later.
    func();
}

int main() {
    call_function(show_message);
    getch();
}

I've tried some typecasts, but the compiler doesn't accept.
Does anyone here have a suggestion?

Thanks!
