# D3D12_STREAM_OUTPUT_DESC

> Describes a streaming output buffer.

Describes a streaming output buffer.

## Syntax

```cpp theme={null}
typedef struct D3D12_STREAM_OUTPUT_DESC
{
    const D3D12_SO_DECLARATION_ENTRY  pSODeclaration;
    UINT NumEntries;
    const UINT  pBufferStrides;
    UINT NumStrides;
    UINT RasterizedStream;
} D3D12_STREAM_OUTPUT_DESC
```

### Members

*pSODeclaration*\
Type: const D3D12\_SO\_DECLARATION\_ENTRY \*

An array of [D3D12\_SO\_DECLARATION\_ENTRY](/reference/graphics/d3d12/structs/d3d12_so_declaration_entry_public) structures. Can't be **NULL** if **NumEntries** > 0.

*NumEntries*\
Type: UINT

The number of entries in the stream output declaration array that the **pSODeclaration** member points to.

*pBufferStrides*\
Type: const UINT \*

An array of buffer strides; each stride is the size of an element for that buffer.

*NumStrides*\
Type: UINT

The number of strides (or buffers) that the **pBufferStrides** member points to.

*RasterizedStream*\
Type: UINT

The index number of the stream to be sent to the rasterizer stage.

## Remarks

A [D3D12\_GRAPHICS\_PIPELINE\_STATE\_DESC](/reference/graphics/d3d12_x/structs/d3d12_graphics_pipeline_state_desc) object contains a **D3D12\_STREAM\_OUTPUT\_DESC** structure.

## Requirements

**Header:** d3d12\_xs.h or d3d12\_x.h\
**Library:** d3d12\_xs.lib or d3d12\_x.lib\
**Supported Platforms**: XBOX Series consoles and XBOX One family
