Bug 1952

Summary: SDL_calloc might returns NULL in SDL_CreateWindow(const char *title, int x, int y, int w, int h, Uint32 flags) function
Product: SDL Reporter: Nitz <nitin.j4>

Description Nitz 2013-07-10 05:18:00 UTC 
In function:
SDL_Window *
SDL_CreateWindow(const char *title, int x, int y, int w, int h, Uint32 flags)
{
   // Some Code

   window = (SDL_Window *)SDL_calloc(1, sizeof(*window));// In this SDL_calloc sometimes might return NULL.   

   // Some Code
}
In above function SDL_calloc sometimes might return NULL to window, which is not accepted.
So to avoid this, patch should be:

window = (SDL_Window *)SDL_calloc(1, sizeof(SDL_Window));

Thanks,
Nitz

The sizeof() is fine, but you're right that it needs to check the return value of SDL_calloc().

This is now fixed, thanks!
