[−][src]Function fermium::video::SDL_GL_SetSwapInterval

pub unsafe extern "C" fn SDL_GL_SetSwapInterval(interval: c_int) -> c_int

Sets the swap interval of GL swaps.

  • 0 for immediate swapping.
  • 1 for standard vsync swapping.
  • -1 for adaptive vsync swapping.

Some systems will not support adaptive vsync but still support standard vsync.

Returns: 0 on success, -1 if setting the swap interval isn't supported. Call SDL_GetError for more.
