# PartyAudioManipulationSourceStream::GetAvailableBufferCount

> 检索可从此流通过检索的缓冲区总数。

检索可通过 [PartyAudioManipulationSourceStream::GetNextBuffer()](https://docs.xbox.com/zh-CN/services/playfab/multiplayer/networking/reference/classes/PartyAudioManipulationSourceStream/methods/partyaudiomanipulationsourcestream_getnextbuffer.md) 从此流检索的缓冲区总数。

## 语法

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

### 参数

**`count`**   uint32\_t\*
*输出*

可用缓冲区的输出计数。

### 返回值

PartyError

如果调用成功,则返回 `c_partyErrorSuccess`;否则返回错误代码。可以通过 [PartyManager::GetErrorMessage()](https://docs.xbox.com/zh-CN/services/playfab/multiplayer/networking/reference/classes/PartyManager/methods/partymanager_geterrormessage.md) 检索错误代码的人类可读形式。

## 备注

如果调用方倾向于以批处理方式通过其管道发送音频缓冲区,这可能会很有用。由于此缓冲区计数受通过 [PartyChatControl::ConfigureAudioManipulationVoiceStream()](https://docs.xbox.com/zh-CN/services/playfab/multiplayer/networking/reference/classes/PartyChatControl/methods/partychatcontrol_configureaudiomanipulationvoicestream.md) 指定的最大音频队列大小限制,因此调用方应给予音频处理管道充足的时间来处理缓冲区,并将它们通过 [PartyAudioManipulationSourceStream::ReturnBuffer()](https://docs.xbox.com/zh-CN/services/playfab/multiplayer/networking/reference/classes/PartyAudioManipulationSourceStream/methods/partyaudiomanipulationsourcestream_returnbuffer.md) 归还,以防止音频丢失。
