HRESULT CheckStreaming( );
Return Values
Returns one of the following HRESULTvalues, depending on the state.
| S_FALSE | Currently in flushing state. |
| S_OK | Receiveor EndOfStreamoperations can safely proceed. |
| VFW_E_NOT_CONNECTED | The output pin either does not exist or isn't connected. |
| VFW_E_RUNTIME_ERROR | A run-time error occurred when processing a previous sample. |

Remarks
This member function overrides the CBaseInputPin::CheckStreamingmember function and calls that base class implementation for most of the condition checks. It determines if the pin is connected, if it is in a paused or running state, and if it is not currently flushing data or processing a run-time error.
