# D3D12_STREAM_OUTPUT_DESC

> 描述流输出缓冲区。

描述流输出缓冲区。

## 语法

```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
```

### 成员

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

一个 [D3D12\_SO\_DECLARATION\_ENTRY](/reference/graphics/d3d12/structs/d3d12_so_declaration_entry_public) 结构数组。如果 **NumEntries** > 0，则不能为 **NULL**。

*NumEntries*\
类型：UINT

**pSODeclaration** 成员所指向的流输出声明数组中的条目数。

*pBufferStrides*\
类型：const UINT \*

缓冲区跨距数组；每个跨距是该缓冲区一个元素的大小。

*NumStrides*\
类型：UINT

**pBufferStrides** 成员所指向的跨距（或缓冲区）数量。

*RasterizedStream*\
类型：UINT

要发送到光栅化器阶段的流的索引号。
