SDL_GL_SwapWindow

Update a window with OpenGL rendering.

Syntax

void SDL_GL_SwapWindow(SDL_Window * window);

Function Parameters

window

the window to change

Remarks

This is used with double-buffered OpenGL contexts, which are the default.

On macOS, make sure you bind 0 to the draw framebuffer before swapping the window, otherwise nothing will happen. If you aren't using glBindFramebuffer(), this is the default and you won't have to do anything extra.

Version

This function is available since SDL 2.0.0.
