/* CV, 2005-09-08: The CTRL_LOGOFF_EVENT is only send to services.
It's send when *any* user logs off. Services generally have
a modified console handler which allows services to survive
also after a user logged out, even if the service has a console
window attached to the visible window station of the user
("Interact with desktop"). The below code contradicts this
standard behaviour, so for now, we disable it and just return
FALSE to get the default behaviour or the one the application's
own console handler (if any) requires.
In other words: We never send SIGHUP to services and their
child processes on a LOGOFF event. */
/* Check if the process is actually associated with a visible
window station, one which actually represents a visible desktop.
If not, the CTRL_LOGOFF_EVENT doesn't concern this process. */
