SwNtfy Fn 0006H: Switcher Is Destroying a Session
Expect: AX 0006H
BX ID of the session
ES:DI addr of switcher's service-entry address
Return: AX 0000H (you must return 0 in all cases)
Info: Task switchers call this to let you know that a session is about
to be destroyed. It gives you a chance perform any cleanup
needed to process the end of a session.
When called, interrupts are enabled you may use all DOS fns.
BX will contain the session ID of the session that is about to be
destroyed. (Note: it need not be the current active session).
ES:SI will contain the task switcher's service entry address. Use this
address if you need to call any task-switcher service fns.
Return: AX=0000H you must return 0. Tasks have not veto power here.
Notes: You may get this call without first seeing a SwNtfyFn 0006H
(session is being created). That call is broadcasted when some
task has vetoed the new session. In that case, you may ignore
