IOleUndoManager::EnumRedoable
Creates an
enumerator object that the caller can use to iterate through a series of
top-level undo units from the redo stack.
HRESULT EnumRedoable(
|
IEnumOleUndoUnits** ppEnum |
//Indirect pointer to new enumerator object |
|
); |
|
Parameters
ppEnum
[out]
Indirect pointer to the IEnumOleUndoUnits interface on the enumerator
object.
Return Values
S_OK
The
enumerator object was successfully created and the interface pointer was
returned.
E_UNEXPECTED
The undo
manager is disabled.
Remarks
A new
enumerator object is created each time this method is called. If the series of
enumerated items changes over time, the results of enumeration operations can
vary from one call to the next.
This method
calls AddRef on the new enumerator object to increment its reference
count. The caller is responsible for calling Release on the enumerator
object when it is no longer needed.
