C++/VB - Where to find document for IID_IT...

Is there a document page for the interface IDs?  For example,

pAddress->QueryInterface(IID_ITMediaSupport,(void **)&pMediaSupport);

I searched for "IID_ITMediaSupport" and can only find it being used in a
sample code.  I see a few more defined in Tapi3if.h, but it is not quite
clear what they are for.  Is there any documentation or I will need to
look at the sample codes?

Chu,
none that I know of.


I have seen it being defined in TAPI3IF.H and TAPI3.H,
used in "Select an Address" MSDN code snippet and some P-SDK samples
(tapisend, tapirecv, Incoming, Outgoing, FileTerm, AnsMach, acdclient).
