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.

punkDocData
Type: System.IntPtr
[out, optional] Returns the IUnknown interface.

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 handles all cases to add a lock to a document whether the document is already registered or not. This is a convenience method that combines the functionality of RegisterAndLockDocument and FindAndLockDocumentEx. RegisterAndLockDocument returns an error if the document is already registered. FindAndLockDocumentEx returns an error if it is not registered. In the case where an RDT_EditLock is desired and the document is currently registered only with a RDT_ReadLock with no pHier/itemid assigned, this function will assign the preferred pHier/itemid to the document.
