The IBDA_PinControl interface is exposed on a BDA device filter’s pins. A Network Provider calls these methods to determine the type and identifier of each pin on the filter. A Network Provider uses this information when building the graph.
In addition to the methods inherited from IUnknown, the IBDA_PinControl interface exposes the following methods.
| Method | Description |
| GetPinID | Retrieves the identifier of the pin. |
| GetPinType | Retrieves the type of the pin. |
| RegistrationContext | Retrieves the registration context of a particular pin. |
