HRESULT GetBufferNotifySize(
ULONG *pcbSize
);
Parameters
- pcbSize
- [out] Address of the size information, specified in bytes, that is associated with the audio stream buffer.
Return values
| Value | Description |
|---|---|
| S_OK | Function completed successfully. |

Remarks
For read streams, the event is set if the audio buffered is greater than or equal to the value set in pcbSize, otherwise the event information is reset.
For write streams, the event is set if the audio buffered is less than the value set in pcbSize, otherwise the event information is reset.
