NAME

       SDL_SetWindowSurfaceVSync - Toggle VSync for the window surface.

SYNOPSIS

       #include <SDL3/SDL_video.h>

       bool SDL_SetWindowSurfaceVSync(SDL_Window *window, int vsync);

       #define SDL_WINDOW_SURFACE_VSYNC_DISABLED 0
       #define SDL_WINDOW_SURFACE_VSYNC_ADAPTIVE (-1)

DESCRIPTION

       When a window surface is created, vsync defaults to SDL_WINDOW_SURFACE_VSYNC_DISABLED.

       The vsync parameter can be 1 to synchronize present with every vertical refresh, 2 to synchronize present
       with  every  second  vertical  refresh,  etc.,  SDL_WINDOW_SURFACE_VSYNC_ADAPTIVE  for  late swap tearing
       (adaptive vsync), or SDL_WINDOW_SURFACE_VSYNC_DISABLED to disable. Not every value is supported by  every
       driver, so you should check the return value to see whether the requested setting is supported.
