CBaseFilter::EnumPins (Compact 2013)

  • Artigo

3/26/2014

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.
