# GetShapeDmaReadWriteFull

Gets a 32-bit value that contains the read and write pointers and the buffer-full flag.

## Syntax

```cpp theme={null}
SHAPE_DMA_READ_WRITE_FULL GetShapeDmaReadWriteFull(  
         const SHAPE_DMA_CONTEXT* context  
)  
```

### Parameters

*context*   \_In\_\
Type: [SHAPE\_DMA\_CONTEXT\*](/reference/audio/shapedmacontext/structs/shape_dma_context)

Pointer to a [SHAPE\_DMA\_CONTEXT](/reference/audio/shapedmacontext/structs/shape_dma_context) structure.

### Return value

Type: SHAPE\_DMA\_READ\_WRITE\_FULL

32-bit value that contains the read pointer, the write pointer, and the buffer-full flag. Refer to the [SHAPE\_DMA\_READ\_WRITE\_FULL](/reference/audio/shapedmacontext/structs/shape_dma_read_write_full) structure.

## Remarks

This atomic operation guarantees that the three values are in sync.

Any additional Scalable Hardware Audio Processing Engine (SHAPE) processing is performed by reading and writing to temporary mix buffers. The processing performed is controlled by the Audio Control Processor (ACP), which itself is driven by the application through the [AcpHal](/reference/audio/acphal/acphal_members) API. These processes include equalizing, compression, filter scaling, and volume scaling.

## Requirements

**Header:** shapedmacontext.h

**Supported platforms:** XBOX One family consoles and XBOX Series consoles
