# SetShapeXmaCurrentInputBuffer

Sets the current input buffer.

<a id="syntaxSection" />

## Syntax

```cpp theme={null}
HRESULT SetShapeXmaCurrentInputBuffer(  
         SHAPE_XMA_CONTEXT* context,  
         UINT32 currentBuffer  
)  
```

<a id="parametersSection" />

### Parameters

*context*   \_Inout\_\
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.

*currentBuffer*   \
Type: UINT32

The current input buffer. 0 specifies the left buffer, and 1 specifies the right buffer.

<a id="retvalSection" />

### Return value

Type: HRESULT

HRESULT success or error code.

## Remarks

To set the address of the left input buffer, use [SetShapeXmaInputBuffer0(SHAPE\_XMA\_CONTEXT\*, const void\*)](/reference/audio/shapexmacontext/functions/setshapexmainputbuffer0) or [SetShapeXmaInputBuffer0(SHAPE\_XMA\_CONTEXT\*, APU\_ADDRESS)](/reference/audio/shapexmacontext/functions/setshapexmainputbuffer0_2). To set the address of the right input buffer, use [SetShapeXmaInputBuffer1(SHAPE\_XMA\_CONTEXT\*, const void\*)](/reference/audio/shapexmacontext/functions/setshapexmainputbuffer1) or [SetShapeXmaInputBuffer1(SHAPE\_XMA\_CONTEXT\*, APU\_ADDRESS)](/reference/audio/shapexmacontext/functions/setshapexmainputbuffer1_2).

To get the current input buffer, use [GetShapeXmaCurrentInputBuffer](/reference/audio/shapexmacontext/functions/getshapexmacurrentinputbuffer).
