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?
