IConnectionPoint::GetConnectionInterface method (ocidl.h)
Retrieves the IID of the outgoing interface managed by this connection point.
Syntax
HRESULT GetConnectionInterface(
[out] IID *pIID
);
Parameters
[out] pIID
A pointer to the identifier of the outgoing interface managed by this connection point.
Return value
This method can return the standard return value E_UNEXPECTED, as well as the following values.
| Return code | Description |
|---|---|
|
The caller's variable pIID contains the identifier of the outgoing interface managed by this connection point. |
|
The address in pIID is not valid. For example, it may be NULL. |
Remarks
Using the IEnumConnectionPoints interface, a client can obtain a pointer to the IConnectionPoint interface. Using that pointer and the GetConnectionInterface method, the client can determine the IID of each connection point enumerated. The IID returned from this method must enable the caller to access this same connection point through IConnectionPointContainer::FindConnectionPoint.
Notes to Implementers
This method must be implemented in any connection point; E_NOTIMPL is not an acceptable return value.Requirements
