[SDL] BMP is not drawed

[Albert Fernández Marsal]

	Well, this time I think I know the answer :).

	the function should look like:

	int initgame(SDL_Surface **target) // Notice de *pointer to pointer*
parametere!!!
	(...)
	*target = SDL_SetVideoMode(...); // the call to SDL_SetVideoMode
will look like this

	otherwise, the pointer is not modified!

	Hope this time is the right answer.

Hmmm strange.

I've got a header named main.h in this header is a function:

------------------------------------------------------------
/* Diese Funktion initalisiert SDL und setzte den Videomodus. */
int initgame(SDL_Surface *target) {
   if (SDL_Init(SDL_INIT_VIDEO) < 0) {
      fprintf(stderr, "SDL konnte nicht initialisiert werden: %s\n",
                       SDL_GetError());
      exit(1);
   }

   /* Videomodus setzen */
   target = SDL_SetVideoMode(640, 480, 0, 0);
   if (!target) {
      fprintf(stderr, "Konnte Bildschirmmodus nicht setzen: %s\n",
                       SDL_GetError());
      exit(2);
   }

   /* Netzwerkunterstützung aktivieren */
   if(SDLNet_Init() < 0) {
      fprintf(stderr, "Konnte Netzwerk nicht initialisieren: %s\n",
SDLNet_GetError());
      exit(3);
   }
   return 0;
}

---------------------------------------------------------------------

It's called in main() with "initgame(screen)". If I use these funtion the
screen stays black, no bmp is drawed. If I don't us the function and do
write the orders in the function directly to main() the bmp is drawed. I
can't say why.

By the way do you know a good debugger for windows?
