NAME

       SDL_GetWindowSurface - Get the SDL surface associated with the window.

SYNOPSIS

       #include <SDL3/SDL_video.h>

       SDL_Surface * SDL_GetWindowSurface(SDL_Window *window);

DESCRIPTION

       A  new surface will be created with the optimal format for the window, if necessary. This surface will be
       freed when the window is destroyed. Do not free this surface.

       This surface will be invalidated if the window is resized. After resizing a window this function must  be
       called again to return a valid surface.

       You may not combine this with 3D or the rendering API on this window.

       This function is affected by SDL_HINT_FRAMEBUFFER_ACCELERATION.
