C++ (Cpp) compare_mem Examples

Example #1

File: test_type_equality.c Project: virtualsquare/view-os

static void test_compare_mem(void)
{
  int a[5] = {1,2,3,4,5}; 
  int b[5] = {1,2,3,4,5};
  int c[5] = {1,2,3,4,10};

  assert(compare_mem(a,b,(sizeof(int) * 5)));
  assert(!compare_mem(a,c,(sizeof(int) * 5)));
}

Example #2

File: screen.c Project: ozkriff/roguelikeInLua

static int screen_compare(lua_State *L) {
  Screen *screen;
  SDL_Surface *real;
  SDL_Surface *tmp;
  SDL_Surface *expected;
  int is_equal;
  int size;
  int bpp_real;
  int bpp_expected;
  screen = check_screen(L, 1);
  real = screen->screen;
  bpp_real = real->format->BytesPerPixel;
  tmp = IMG_Load(lua_tostring(L, 2));
  /* convert to screen format */
  expected = SDL_DisplayFormat(tmp);
  bpp_expected = expected->format->BytesPerPixel;
  SDL_FreeSurface(tmp);
  bpp_real = expected->format->BytesPerPixel;
  assert(expected);
  assert(bpp_real == bpp_expected);
  assert(real->w == expected->w);
  assert(real->h == expected->h);
  size = expected->w * expected->h * bpp_expected;
  is_equal = compare_mem(real->pixels, expected->pixels, size);
  SDL_FreeSurface(expected);

  return 1;
