CEnumPins class

CEnumPins Class Hierarchy

The CEnumPins class implements an enumerator for pins.

This class implements the IEnumPins interface. It calls the following CBaseFilter methods:

If the filter dynamically creates or destroys pins, it increments the pin version whenever the pins change. If the version number changes, the enumerator object is no longer synchronized with the filter. Once the enumerator is out of sync, the methods in CEnumPins return VFW_E_ENUM_OUT_OF_SYNC. Call the CEnumPins::Reset method to resynchronize the enumerator.
