IVsTextBuffer.GetLanguageServiceID(Guid%)

Remarks

COM Signature

From textmgr.idl:

HRESULT IVsTextStream::GetLanguageServiceID(
   [out] GUID *pguidLangService
);

This method could require considerable resources, depending upon the underlying implementation of the buffer. That is, it could be very difficult to calculate the size of the buffer if it is a virtual-line-oriented implementation of the buffer, as in Visual Basic.
