SDL_GL_SwapBuffers currently returns a void and does not set any errors.

This means an application cannot check if an error occurred. In some cases the application may want to bail out if it cannot swap buffers rather than loop not rendering anything to the screen.

This may not be relevant to all video targets as some may have errored elsewhere but this should be fairly simple to implement for eglSwapBuffers which returns a boolean. Everything else could just return success.

You may say that this should not occur but it certainly can in the case of EGL even after eglMakeCurrent has passed. This is most likely a driver bug but could also be due to context race conditions.

Makes sense. Would you like to create a patch to implement this?

It was implemented for SDL_GL_SwapWindow() to resolve bug 3513.

I was actually intending to refer to SDL_GL_SwapWindow got confused with old SDL and new SDL :)
