# sharegroup

The context’s sharegroup object. (read-only)

```
var sharegroup: EAGLSharegroup { get }
```

## Discussion

Retrieve the sharegroup of a context when you want to create two or more contexts that share rendering resources. Call [`init(api:)`](/documentation/OpenGLES/EAGLContext/init(api:)-q09o) to initialize the first context, retrieve its sharegroup, and then initialize additional contexts by calling [`init(api:sharegroup:)`](/documentation/OpenGLES/EAGLContext/init(api:sharegroup:)-2rt8m), passing this sharegroup as the parameter.

## See Also

[`init?(api: EAGLRenderingAPI, sharegroup: EAGLSharegroup)`](/documentation/OpenGLES/EAGLContext/init(api:sharegroup:)-2rt8m)

Initializes and returns a newly allocated rendering context with the specified version of OpenGL ES rendering API and the specified sharegroup.
