Subject: DECAda/VMS - calling GETJPI

Message-ID: <31B2AF74.668E@dial.eunet.ch> (raw)
Here's one for the VMS gurus (I can't post it to comp.os.vms,
'cos there's a psychopath there who throws abuse at me):
I want to examine all processes currently active. The system
service to do this is, of course, GetJPI (either in Starlet or
Lib). To perform wildcard process search, this procedure
expects to receive a value of -1 for the process_id parameter.
Unfortunately, in the "official" spec-files for these
procedures, this parameter has the type UNSIGNED_LONGWORD. Ada,
quite correctly, objects to this kind of thing :-)
So, what I now do is the following:
PID : UNSIGNED_LONGWORD;
PID0 : INTEGER;
for PID0 use at PID'address;
begin
PID0 := -1;
loop
GetJPI(..., Process_Id => PID, ...);
This works, but I can't help but wonder if there isn't a more
elegant way to do it. Does anyone have experience with this?
