IPinFlowControl Interface
Blocks data flow from an active output pin. This interface is exposed by output pins that can reconnect dynamically. Use this interface to start a dynamic reconnection within the filter graph. For more information, see Dynamic Graph Building.
Filter developers: Parser and capture filters that support dynamic reconnection should support this interface on their output pins. Generally, other types of filters do not need to implement this interface.
In addition to the methods inherited from IUnknown, the IPinFlowControl interface exposes the following method.
| Method | Description |
| Block | Blocks or unblocks the flow of data from the pin. |
