COM Signature

From textmgr.idl:

C++

HRESULT IVsCompletionSet::GetInitialExtent(
   [out] long *piLine,
   [out] long *piStartCol,
   [out] long *piEndCol
);

Use this method to tell the view where to place the completion box. By specifying values for piLine, piCol and piLen, you are indicating a span of text that the view should not obscure with the completion box. If the value of the piLen parameter is set to zero, then an anchor coordinate (piCol, piLine) must be provided.
