first allegro program

the program runs just fine everything goes as it should but i get a warning in my messages. it says this...

[Warning] passing NULL used for non-pointer converting 6 of `int al_show_native_message_box(ALLEGRO_DISPLAY*, const char*, const char*, const char*, const char*, int)'

and this is my code. what exactly does this mean?

all i am doing is making a window and destroying it.


int main(int argc, char **argv)
{
   ALLEGRO_DISPLAY *display = NULL;
   
   if(!al_init())
   {
        al_show_native_message_box(NULL, NULL, NULL, "Failed to initialize allegro!", NULL, NULL);
        
        return -1;
   }

Last parameter is an int, not a pointer. So compiler warns you about possible accidental code. What does last parameter means? If you need it to be 0, make it 0, not NULL

cool. thanks a lot. changed it to 0 and the warning went away. :)
