Parameters

• docCookie
  Type: System.UInt32
  [in] Abstract value representing the document for which information was requested.

• pgrfRDTFlags
  Type: System.UInt32%
  [out] Returns flags whose values are taken from the _VSRDTFLAGS enumeration.

• pdwReadLocks
  Type: System.UInt32%
  [out] Returns the number of read locks on the document.

• pdwEditLocks
  Type: System.UInt32%
  [out] Returns the number of edit locks on the document.

• pbstrMkDocument
  Type: System.String%
  [out] Returns the path and file name of the document.

• ppHier
  Type: Microsoft.VisualStudio.Shell.Interop.IVsHierarchy%
  [out, optional] Returns the IVsHierarchy interface.

• pitemid
  Type: System.UInt32%
  [out, optional] Item identifier of the document. This is a unique identifier or it can be one of the following values: VSITEMID_NIL, VSITEMID_ROOT, or VSITEMID_SELECTION.

• ppunkDocData
  Type: System.IntPtr%
  [out, optional] Returns an IUnknown interface.

Return Value

Type: System.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::GetDocumentInfo(
   [in] VSCOOKIE        docCookie,
   [out] VSRDTFLAGS    *pgrfRDTFlags,
   [out] DWORD         *pdwReadLocks,
   [out] DWORD         *pdwEditLocks,
   [out] BSTR          *pbstrMkDocument,
   [out] IVsHierarchy **ppHier,
   [out] VSITEMID      *pitemid,
   [out] IUnknown     **ppunkDocData
);

The ppunkDocData parameter represents the document data object associated with the registered document. Typically, the IVsPersistDocData and IVsDocDataFileChangeControl interfaces are obtained from this IUnknown object.
