4 * PURPOSE: GUI state check
5 * FILE: win32ss/user/ntuser/guicheck.c
6 * PROGRAMER: Casper S. Hornstrup (chorns@users.sourceforge.net)
7 * NOTES: The GuiCheck() function performs a few delayed operations:
8 * 1) A GUI process is assigned a window station
9 * 2) A message queue is created for a GUI thread before use
10 * 3) The system window classes are registered for a process
