* Name: nxtk_opentoolbar
*
* Description:
* Create a tool bar at the top of the specified framed window
*
* Input Parameters:
* hfwnd - The handle returned by nxtk_openwindow
* height - The request height of the toolbar in pixels
* cb - Callbacks used to process toolbar events
* arg - User provided value that will be returned with toolbar
* callbacks.
*
* Returned Value:
* OK on success; ERROR on failure with errno set appropriately
