NAME

SDL_GL_SwapWindow - Update a window with OpenGL rendering.

SYNOPSIS

#include <SDL3/SDL_video.h>

bool SDL_GL_SwapWindow(SDL_Window *window);

DESCRIPTION

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.

RETURN VALUE

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

THREAD SAFETY
