* 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.
