3.1.3 IMG_Quit

void IMG_Quit()

This function cleans up all dynamically loaded library handles, freeing memory. If support is required again it will be initialized again, either by IMG_Init or loading an image with dynamic support required. You may call this function when IMG_Load functions are no longer needed for the JPG, PNG, and TIF image formats. You only need to call this function once, no matter how many times IMG_Init was called.

// unload the dynamically loaded image libraries IMG_Quit();
