Finding which applications have what privileges on a call

[fdecker]

LINEDEVSTUS gives the number of opens on a call and the number of
owners and monitors. The LINEAPPINFO structure lists all the
applications that have the line open. LINECALLSTATUS gives us the
privileges for the current app for a call. Can an application find
which *other* applications have ownership or monitor privileges on a
call? In other words, from inside MY app, can I see what another TAPI
app's privileges are for the same call?

Fred,
AFAIK you cannot (in general).

As you already did found oot your app only knows for sure about its own
owner/monitor status on a call,
and the total number of monitors/owners on a call, and the list of all app
using the line device.
In some scenarios these infos will be suffcicient to make conclusions about
another app:
if there is only one other app then you get the privs of this other app by
just "substracting" your privs from the total privs.
