Parameters

  • pszMkDocument
    Type: System.String
    [in] Path to the located document.
  • punkDocData
    Type: System.IntPtr
    [out, optional] Returns the IUnknown interface.
  • 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.

COM Signature
