Function SDL_GL_GetSwapInterval

pub unsafe extern "C" fn SDL_GL_GetSwapInterval(
    interval: *mut i32,
) -> bool
Available on crate feature dep_sdl3 only.
Expand description

Get the swap interval for the current OpenGL context.

If the system can’t determine the swap interval, or there isn’t a valid current context, this function will set *interval to 0 as a safe default.

§Parameters

  • interval: output interval value. 0 if there is no vertical retrace synchronization, 1 if the buffer swap is synchronized with the vertical retrace, and -1 if late swaps happen immediately instead of waiting for the next retrace.

§Return value

Returns true on success or false on failure; call SDL_GetError() for more information.

§Thread safety

This function should only be called on the main thread.

§Availability

This function is available since SDL 3.2.0.
