Is Viewport Clipped?

Does anyone know how lisp can determine if an mview viewport has been
clipped or not? I don't see any difference between an entget on a clipped
viewport and an unclipped viewport. I'm wanting to use "(command "vpclip"
........) but the number of responses depends on whether the vp is clipped or
not.

 

On my viewports any clipping pline is right on top; just highlight it and glance
at the Properties window. If you have chosen a clipped vp there will be 2
objects listed. They cannot be separated but you can alter the pline if you wish
to make it identifiable.

OK, so I guess that means a pline is always associated with a clipped
viewport; but I still don't understand how LISP can be made aware of it ???
I'm wanting a lisp program to know it, not necessarily the user.

 

I'm brain-dead. I asked the wrong question. I meant xclip, not vpclip. So
restating the question:

Does anyone know how lisp can determine if an xref has been clipped or not?
I don't see any difference between an entget on a clipped xref and an
unclipped xref. I'm wanting to use "(command "xclip" .......) but the
number of responses depends on whether the xref is clipped or not.

 

Here is what I get on the same xref, before & after an xclip.....

((-1 . <Entity name: 40082f58>) (0 . "INSERT") (330 . <Entity name:
40082cf8>) (5 . "6B") (100 . "AcDbEntity") .......
_$
((-1 . <Entity name: 40082f58>) (0 . "INSERT") (5 . "6B") (102 .
"{ACAD_XDICTIONARY") (360 . <Entity name: 40082f60>) (102 . "}") (330 .
<Entity name: 40082cf8>) (100 . "AcDbEntity") .......

Note the 102 & 360 group codes.....
