Remarks

COM Signature

From vsshell.idl:

HRESULT IVsRunningDocumentTable::RegisterDocumentLockHolder(
   [in] VSREGDOCLOCKHOLDER     grfRDLH,
   [in] VSCOOKIE               dwCookie,
   [in] IVsDocumentLockHolder *pLockHolder,
   [out] VSCOOKIE             *pdwLHCookie
);

Use this identifier returned in the pdwLHCookie parameter to unregister the document lock holder by calling the UnregisterDocumentLockHolder method.

The dwCookie parameter is same value that is returned from the FindAndLockDocument or RegisterAndLockDocument methods.
