+ * Name: nx_constructwindow
+ *
+ * Description:
+ *   This function is the same a nx_openwindow EXCEPT that the client provides
+ *   the window structure instance.  nx_constructwindow will initialize the
+ *   the pre-allocated window structure for use by NX.  This function is
+ *   provided in addition to nx_open window in order to support a kind of
+ *   inheritance:  The caller's window structure may include extensions that
+ *   are not visible to NX.
+ *
+ *   NOTE:  wnd must have been allocated using kmalloc() (or related allocators)
+ *   Once provided to nx_constructwindow() that memory is owned and managed
+ *   by NX.  On certain error conditions or when the window is closed, NX will
+ *   free the window.
+ *
+ * Input Parameters:
+ *   handle - The handle returned by nx_connect
+ *   wnd    - The pre-allocated window structure.
+ *   cb     - Callbacks used to process window events
+ *   arg    - User provided value that will be returned with NX callbacks.
+ *
+ * Return:
+ *   OK on success; ERROR on failure with errno set appropriately.  In the
+ *   case of ERROR, NX will have deallocated the pre-allocated window.
+ *
