# GetShapeXmaOutputBufferNumBytesAvailable

Gets the number of bytes available for reading from the output buffer.

<a id="syntaxSection" />

## Syntax

```cpp theme={null}
UINT32 GetShapeXmaOutputBufferNumBytesAvailable(  
         const SHAPE_XMA_CONTEXT* context  
)  
```

<a id="parametersSection" />

### Parameters

*context*   \_In\_\
Type: [SHAPE\_XMA\_CONTEXT](/reference/audio/shapexmacontext/structs/shape_xma_context)\*

Pointer to a [SHAPE\_XMA\_CONTEXT](/reference/audio/shapexmacontext/structs/shape_xma_context) object.

<a id="retvalSection" />

### Return value

Type: UINT32

Number of bytes available for reading.

## Remarks

To get the number of frames available for reading, use [GetShapeXmaOutputBufferNumFramesAvailable](/reference/audio/shapexmacontext/functions/getshapexmaoutputbuffernumframesavailable).

To get the current read offset of the output buffer, use [GetShapeXmaOutputBufferReadOffset](/reference/audio/shapexmacontext/functions/getshapexmaoutputbufferreadoffset).

For more information, see the [XMA](/build/console-features/audio/overviews/shape-overview#ID4EYD) section of [Overview of SHAPE](/build/console-features/audio/overviews/shape-overview).
