Retrieves an IEnumPinspointer that can be used to enumerate all the pins available on this filter.
HRESULT EnumPins( IEnumPins ** ppEnum );
Parameters
- ppEnum
- Pointer to the
IEnumPinsinterface to
retrieve.
Return Values
Returns E_OUTOFMEMORY if a new enumerate could not be created or NOERROR if successful.
Remarks
This member function implements the IBaseFilter::EnumPinsmethod. It uses the CEnumPinsobject to construct an enumerator and retrieves the IEnumPinsinterface from the CEnumPinsobject. The implementation of CEnumPins::Nextcalls the CBaseFilter::GetPinmember function, which the derived class must provide. The IEnumPinsinterface is used by the filter graph manager when adding the filter to the filter graph.
