 Posted: Sun Mar 02, 2008 9:39 am Post subject: SDL HWSURFACE freeing patch |
 |
|
While trying to do some fancy stuff using the GU in conjunction with SDL, I noticed that it was impossible to SDL_FreeSurface a hardware surface. After doing some research, I noticed that SDL will only call PSP_FreeHWSurface if surface->hwdata is non-zero. It will also call free on surface->pixels if it is non-zero after calling FreeHWSurface, which obviously won't work if the pixels pointer points to something that isn't in the heap. Therefore, I have created this small patch:
| Code: | --- src/video/psp/SDL_pspvideo.c (revision 2361)
+++ src/video/psp/SDL_pspvideo.c (working copy)
@@ -515,11 +515,13 @@
surface->pitch = pitch;
surface->flags |= SDL_HWSURFACE;
+ surface->hwdata = (void*)1; /* Hack to make SDL realize it's a HWSURFACE when freeing */
return 0;
}
static void PSP_FreeHWSurface(_THIS, SDL_Surface *surface)
{
vidmem_free(surface->pixels);
+ surface->pixels = NULL;
return;
}
