A version of this page is also available for
4/8/2010
Retrieves an IEnumPins pointer that can be used to enumerate all the pins available on this filter.
Syntax
HRESULT EnumPins(
IEnumPins** ppEnum
);
Parameters
- ppEnum
Pointer to the IEnumPins interface to retrieve.
Return Value
Returns E_OUTOFMEMORY if a new enumerate could not be created or NOERROR if successful.
Remarks
This member function implements the IBaseFilter::EnumPins method.
It uses the CEnumPins object to construct an enumerator and retrieves the IEnumPins interface from the CEnumPins object. The implementation of CEnumPins::Next calls the CBaseFilter::GetPin member function, which the derived class must provide.
The IEnumPins interface is used by the filter graph manager when adding the filter to the filter graph.
