AtlUnadvise

Terminates the connection established through AtlAdvise.

HRESULT AtlUnadvise(
   IUnknown* pUnkCP,
   const IID& iid,
   DWORD dw 
);

Parameters

pUnkCP
[in] A pointer to the IUnknown of the object that the client is connected with.
iid
[in] The GUID of the connection point. Typically, this is the same as the outgoing interface managed by the connection point.
dw
[in] The cookie that uniquely identifies the connection.

Return Value

A standard HRESULT value.

Example

LPUNKNOWN m_pSourceUnk;
LPUNKNOWN m_pSinkUnk;
DWORD m_dwCustCookie;

// create source object
HRESULT hr = CoCreateInstance (CLSID_MyComponent, NULL, CLSCTX_ALL, 
         IID_IUnknown, (LPVOID*)&m_pSourceUnk);
_ASSERT (SUCCEEDED (hr));

// Create sink object.  CMySink is a CComObjectRootEx-derived class 
// that implements the event interface methods.
CComObject<CMySink> *pSinkClass;
CComObject<CMySink>::CreateInstance (&pSinkClass);
hr = pSinkClass->QueryInterface (IID_IUnknown, (LPVOID*)&m_pSinkUnk);
_ASSERT (SUCCEEDED (hr));

hr = AtlAdvise (m_pSourceUnk, m_pSinkUnk, IID__IMyEvent, &m_dwCustCookie);
_ASSERT (SUCCEEDED (hr));

// do something

HRESULT hr = AtlUnadvise (m_pSourceUnk, IID__IMyEvent, m_dwCustCookie);
_ASSERT (SUCCEEDED (hr));
