Parameters

grfRDTLockType
Type: UInt32

[in] Flags taken from the _VSRDTFLAGS, _VSRDTFLAGS2, and _VSRDTFLAGS3 enumerations. The flags must include either RDT_EditLock or RDT_ReadLock.

pszMkDocument
Type: String

[in] Path to the document.

pHier
Type: Microsoft.VisualStudio.Shell.Interop.IVsHierarchy

[in] Returns the IVsHierarchy interface of the hierarchy that owns the document. Can only be a null value if a read lock has been obtained.

itemid
Type: UInt32

[in] Item identifier of the document in the hierarchy. This is a unique identifier or it can be one of the following values: VSITEMID_NIL, VSITEMID_ROOT, or VSITEMID_SELECTION.

punkDocData
Type: IntPtr

[in] The IUnknown interface of the document. A null value indicates no document object that can be persisted.

pdwCookie
Type: UInt32%

[out] Returns an abstract value representing the document in the RDT.

Return Value

Type: Int32
If the method succeeds, it returns S_OK. If it fails, it returns an error code.

Remarks

COM Signature

From vsshell.idl:

HRESULT IVsRunningDocumentTable::RegisterAndLockDocument(
   [in] VSRDTFLAGS    grfRDTLockType,
   [in] LPCOLESTR     pszMkDocument,
   [in] IVsHierarchy *pHier,
   [in] VSITEMID      itemid,
   [in] IUnknown     *punkDocData,
   [out] VSCOOKIE    *pdwCookie
);

The punkDocData parameter represents the document data object to be registered. Whatever package that calls the RegisterAndLockDocument method creates that document object which must implement at the very least the IVsPersistDocData and IVsDocDataFileChangeControl interfaces.
