I am writing a program that, in effect, keeps track of which users
are using certain TT: devices.
When I issue $GETDVI with DVI$_PID I always get a pid of 00000042
regardless of which TT: I inquire about. Since the call always
successfully completes I suspect the problem may be linked to the fact
that we are running virtual terminals (we are also running VMS 4.3
if it matters).
Can anyone tell me whether I am right about virtual terminals and,
if so, how I can get the info I'm looking for.
Thanks in advance.

Are you using $GETDVI or $GETDVIW? the difference is in the
synchronicity of the call. Also are you ALWAYS getting a PID
of 00000042? like, if you log off, log in again and try again are
you still getting a PID of 00000042? Are you checking the IOSB (IO
status block) that is specified in the call? it always returns the
actual status of the call in it's low-order word. If you use $GETDVI
on version 4.x systems you have to check the IOSB to see if the
call completed, otherwise you have to use $GETDVIW.
Virtual terminals are devices just like anything else is a device
in VMS, so that should not be your problem. However, to me it sounds
like you may be pointing to the wrong device, or you are always
getting your own PID, or you are not checking the IOSB for the *real*
return status...
