None.
Return Value
Returns one of the following HRESULT values, depending on the state.
| Value | Description |
|---|---|
S_FALSE |
Currently in flushing state. |
S_OK |
Receive or EndOfStream operations can safely proceed. |
The output pin either does not exist or is not connected. |
|
A run-time error occurred when processing a previous sample. |

Remarks
This member function overrides the CBaseInputPin::CheckStreaming member 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.
