# NSOpenGLGetOption

Returns global OpenGL options.

```
extern void NSOpenGLGetOption(NSOpenGLGlobalOption pname, GLint *param);
```

## Discussion

Returns in `param` the value of the global OpenGL parameter `pname`. The available options are enumerated by the [`NSOpenGLGlobalOption`](/documentation/AppKit/NSOpenGLGlobalOption) type.
