# PartyAudioManipulationSourceStream::GetAvailableBufferCount

> 擷取可透過此串流擷取的緩衝區總數。

擷取可透過 [PartyAudioManipulationSourceStream::GetNextBuffer()](https://docs.xbox.com/zh-TW/services/playfab/multiplayer/networking/reference/classes/PartyAudioManipulationSourceStream/methods/partyaudiomanipulationsourcestream_getnextbuffer.md) 從此串流擷取的緩衝區總數。

## 語法

```cpp theme={null}
PartyError GetAvailableBufferCount(  
    uint32_t* count  
)  
```

### 參數

**`count`**   uint32\_t\*\
*輸出*

輸出的可用緩衝區計數。

### 傳回值

PartyError

`c_partyErrorSuccess` (如果呼叫成功)，否則為錯誤碼。可透過 [PartyManager::GetErrorMessage()](https://docs.xbox.com/zh-TW/services/playfab/multiplayer/networking/reference/classes/PartyManager/methods/partymanager_geterrormessage.md) 擷取錯誤碼的人類可讀形式。

## 備註

如果呼叫者偏好以批次緩衝區的方式透過其管線傳送音訊，這會很有用。由於此緩衝區數目受到透過 [PartyChatControl::ConfigureAudioManipulationVoiceStream()](https://docs.xbox.com/zh-TW/services/playfab/multiplayer/networking/reference/classes/PartyChatControl/methods/partychatcontrol_configureaudiomanipulationvoicestream.md) 指定的音訊佇列大小上限所限制，呼叫者應給予其音訊處理管線充裕的時間處理緩衝區，並將其傳回給 [PartyAudioManipulationSourceStream::ReturnBuffer()](https://docs.xbox.com/zh-TW/services/playfab/multiplayer/networking/reference/classes/PartyAudioManipulationSourceStream/methods/partyaudiomanipulationsourcestream_returnbuffer.md)，以防止音訊遺失。
