Syntax

void SDL_GL_GetDrawableSize(SDL_Window* window,
                            int*        w,
                            int*        h)

window	the Window from which the drawable size should be queried
w	a Pointer to variable for storing the width, may be NULL
h	a Pointer to variable for storing the height, may be NULL

This may differ from SDL_GetWindowSize if we're rendering to a high-DPI drawable, i.e. the window was created with SDL_WINDOW_ALLOW_HIGHDPI on a platform with high-DPI support (Apple calls this "Retina"), and not disabled by the SDL_HINT_VIDEO_HIGHDPI_DISABLED hint.

This function is available since SDL 2.0.1.
