Hi Sharon,
thank you for this valuable advice.
Do I understand the source correctly: the requested notification is sent from
STAF as a “special” service request that uses the action “staf_callback” and is
accepted only if the originator of the request is STAF?

Yes, you can register (and unregister) to be notified when a STAF handle no
longer exists via what we call "Handle Garbage Collection". However, we don't
provide documentation for this functionality as it can be a little tricky to
use. If it is used incorrectly it can cause issues.
One of the external STAF services that use "Handle Garbage Collection" is the
Resource Pool (ResPool) service. So, you could look at the source code for the
ResPool service (it is an external C++ service) to see how it is done in
src/staf/services/respool/STAFResPoolService.cpp. It submits a STAF_NOTIFY
REGISTER ONENDOFHANDLE request to the local HANDLE service (which is
undocumented) to add a notification for when a STAF handle (for a specified
STAF instance running on a machine) no longer exists. See the ResPool
service's submitSTAFNotifyRegisterRequest() method. For example:
STAF local HANDLE STAF_NOTIFY REGISTER ONENDOFHANDLE <Handle#> MACHINE
<Endpoint> UUID <uuid> SERVICE <ServiceName> KEY <Key>
And it submits a STAF_NOTIFY UNREGISTER ONENDOFHANDLE request to the local
HANDLE service (which is undocumented) if it wants to remove the notification.
See the ResPool service's submitSTAFNotifyUnregisterRequest() method. For
example.
STAF local HANDLE STAF_NOTIFY UNREGISTER ONENDOFHANDLE <Handle#> MACHINE
<Endpoint> UUID <uuid> SERVICE <ServiceName> KEY <Key>

Subject: [staf-users] STAF service: receive notification if a handle is
deleted
________________________________
Hi,
I would like to write a STAF service, that allows to create instances of a
specific test tool (“MyService CREATE ….”),
pass commands to it (“MyService DOCMD ….”) and terminate the tool (“MyService
DELETE …”).
Each test tool instance would be associated with the STAF handle used while
doing the CREATE.
So it would be fine to have an automatic DELETE on a test tool, when this
handle is deleted.
So, is there a way to be notified on handle deletion?
