3.2.6 IMG_isGIF

int IMG_isGIF(SDL_RWops *src)

src

If the GIF format is supported, then the image data is tested to see if it is readable as a GIF, otherwise it returns false (Zero).

Returns: 1 if the image is a GIF and the GIF format support is compiled into SDL_image. 0 is returned otherwise.

 
// Test sample.gif to see if it is a GIF
SDL_RWops *rwop;
rwop=SDL_RWFromFile("sample.gif", "rb");
if(IMG_isGIF(rwop))
	printf("sample.gif is a GIF file.\n");
else
	printf("sample.gif is not a GIF file, or GIF support is not available.\n");
