* Description:

* to the window and then (2) block any further window messaging.
*
* The 'blocked' callback is the response from nx_block (or nxtk_block).
* Those blocking interfaces are used to assure that no further messages are
* are directed to the window. Receipt of the blocked callback signifies
* that (1) there are no further pending callbacks and (2) that the
* window is now 'defunct' and will receive no further callbacks.
*
* This callback supports coordinated destruction of a window in multi-
* user mode. In multi-use mode, the client window logic must stay
* intact until all of the queued callbacks are processed. Then the
* window may be safely closed. Closing the window prior with pending
* callbacks can lead to bad behavior when the callback is executed.
*
* Multiple user mode only!
*
* Input Parameters:
* wnd - The window to be blocked
* arg - An argument that will accompany the block messages (This is arg2
* in the blocked callback).

* Return:
* OK on success; ERROR on failure with errno set appropriately

* Name: nx_requestbkgd
*
* Description:
* NX normally controls a separate window called the background window.
* It repaints the window as necessary using only a solid color fill. The
* background window always represents the entire screen and is always
* below other windows. It is useful for an application to control the
* background window in the following conditions:
*
* - If you want to implement a windowless solution. The single screen
* can be used to creat a truly simple graphic environment. In this
* case, you should probably also de-select CONFIG_NX_MULTIUSER as well.
* - When you want more on the background than a solid color. For
* example, if you want an image in the background, or animations in the
* background, or live video, etc.
*
* This API only requests the handle of the background window. That
* handle will be returned asynchronously in a subsequent position and
* redraw callbacks.
*
*
* Cautions:
* - The following should never be called using the background window.
* They are guaranteed to cause severe crashes:
*
* nx_setposition, nx_setsize, nx_raise, nx_lower.
*
* - Neither nx_opengbwindow or nx_closebgwindow should be called more than
* once. Multiple instances of the background window are not supported.
*
* Input Parameters:
* handle - The handle returned by nx_connect
* cb - Callbacks to use for processing background window events
* arg - User provided argument (see nx_openwindow, nx_constructwindow)
*
* Return:
* OK: Success; ERROR of failure with errno set appropriately.
