int SDL_GL_MakeCurrent(SDL_Window * window,
                       SDL_GLContext context);

```

| --------------- | ----------------------------------------------- |
| **window**      | the window to associate with the context        |
| **context**     | the OpenGL context to associate with the window |

## Return Value

Returns 0 on success or a negative error code on failure; call
[SDL_GetError](SDL_GetError)() for more information.
