       SDL_ISPIXELFORMAT_FOURCC - A macro to determine if an SDL_PixelFormat
        is a "FourCC" format.


HEADER FILE
       Defined in SDL3/SDL_pixels.h


SYNOPSIS
       #include "SDL3/SDL.h"

       #define SDL_ISPIXELFORMAT_FOURCC(format)  /* The flag is set to 1 because 0x1? is not in the printable ASCII range */ .BI ((format)&&(SDL_PIXELFLAG(format)!=1))


DESCRIPTION
