# PartyAudioManipulationSourceStream::GetNextBuffer

> Obtém o próximo buffer disponível no fluxo.

Obtém o próximo buffer disponível no fluxo.

## Sintaxe

```cpp theme={null}
PartyError GetNextBuffer(  
    PartyMutableDataBuffer* buffer  
)  
```

### Parâmetros

**`buffer`**   [PartyMutableDataBuffer\*](https://docs.xbox.com/pt-BR/services/playfab/multiplayer/networking/reference/structs/partymutabledatabuffer.md)\
*saída*

O buffer de saída. Se nenhum buffer estiver disponível, o campo *bufferByteCount* do PartyMutableDataBuffer será 0 e o campo *buffer* dele será nullptr.

### Valor retornado

PartyError

`c_partyErrorSuccess` se a chamada tiver êxito ou um código de erro caso contrário. A forma legível do código de erro pode ser obtida por meio de [PartyManager::GetErrorMessage()](https://docs.xbox.com/pt-BR/services/playfab/multiplayer/networking/reference/classes/PartyManager/methods/partymanager_geterrormessage.md).

## Comentários

Quando é detectada atividade de voz, um novo buffer fica disponível a cada 40 ms. Caso contrário, nenhum buffer fica disponível. Os buffers recuperados por este método devem ser devolvidos à biblioteca por meio de [PartyAudioManipulationSourceStream::ReturnBuffer()](https://docs.xbox.com/pt-BR/services/playfab/multiplayer/networking/reference/classes/PartyAudioManipulationSourceStream/methods/partyaudiomanipulationsourcestream_returnbuffer.md) quando não estiverem mais sendo usados. \
\
 O número total de buffers disponíveis no momento pode ser recuperado por meio de [PartyAudioManipulationSourceStream::GetAvailableBufferCount()](https://docs.xbox.com/pt-BR/services/playfab/multiplayer/networking/reference/classes/PartyAudioManipulationSourceStream/methods/partyaudiomanipulationsourcestream_getavailablebuffercount.md). Vários buffers podem ser recuperados em sequência antes que qualquer um seja devolvido.   \
\
 Cada buffer está no formato especificado por [PartyAudioManipulationSourceStream::GetFormat()](https://docs.xbox.com/pt-BR/services/playfab/multiplayer/networking/reference/classes/PartyAudioManipulationSourceStream/methods/partyaudiomanipulationsourcestream_getformat.md).   \
\
 Um buffer de dados mutável é fornecido para que o aplicativo possa, opcionalmente, modificar o áudio no próprio local.
