+ * Input Parameters:

+ *   cb     - Callbacks used to process window events
+ *   arg    - User provided value that will be returned with NX callbacks.
+ *
+ * Return:
+ *   Success: A non-NULL handle used with subsequent method calls
+ *   Failure:  NULL is returned and errno is set appropriately
