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.
