Breaks the connection with the event source represented by pUnk.

Syntax

      HRESULT DispEventUnadvise(
   IUnknown* pUnk 
   const IID* piid 
);

Parameters

pUnk
[in] A pointer to the IUnknown interface of the event source object.
piid
A pointer to the IID of the event source object.

Return Value

S_OK or any failure HRESULT value.

Remarks

Once the connection is broken, events will no longer be routed to the handler functions listed in the event sink map.

Note

If your class derives from multiple IDispEventSimpleImpl classes, you will need to disambiguate calls to this method by scoping the call with the particular base class you are interested in.

DispEventAdvise breaks a connection that was established with the event source specified in pdiid.
