Parameters
grfRDTLockType
Type: System.UInt32[in] Flags whose values are taken from the _VSRDTFLAGS enumeration.
pszMkDocument
Type: System.String[in] Path to the located document.
pHierPreferred
Type: Microsoft.VisualStudio.Shell.Interop.IVsHierarchy[out, optional] Returns preferred the IVsHierarchy interface for the located document.
itemidPreferred
Type: System.UInt32[out, optional] Returns an item identifier of the located document. This is a unique identifier or it can be one of the following values: VSITEMID_NIL, VSITEMID_ROOT, or VSITEMID_SELECTION.
ppHierActual
Type: Microsoft.VisualStudio.Shell.Interop.IVsHierarchy%[out, optional] Returns the actual IVsHierarchy interface for the located document.
pitemidActual
Type: System.UInt32%[out, optional] Returns an item identifier of the located document. This is a unique identifier or it can be one of the following values: VSITEMID_NIL, VSITEMID_ROOT, or VSITEMID_SELECTION.
ppunkDocDataActual
Type: System.IntPtr%[out, optional] Returns the IUnknown interface.
pdwCookie
Type: System.UInt32%[out, optional] Returns an abstract value for the document.
Return Value
Type: System.Int32
If the method succeeds, it returns S_OK. If it fails, it returns an error code.
Remarks
This method is similar to FindAndLockDocument but also allows the specification of a preferred hierarchy/itemid pair for the document in case an RDT_EditLock is desired and the document is currently registered with only a RDT_ReadLock with no hierarchy/itemid assigned. In this case FindAndLockDocument would have returned E_UNEXPECTED. This method will not register the document in the Running Document Table if it is not currently registered.
