# D3D12_WRITEBUFFERIMMEDIATE_MODE

> 指定 WriteBufferImmediate 操作使用的模式。

指定 **WriteBufferImmediate** 操作使用的模式。

## 语法

```cpp theme={null}
typedef enum D3D12_WRITEBUFFERIMMEDIATE_MODE
{
    D3D12_WRITEBUFFERIMMEDIATE_MODE_DEFAULT = 0,
    D3D12_WRITEBUFFERIMMEDIATE_MODE_MARKER_IN = 1,
    D3D12_WRITEBUFFERIMMEDIATE_MODE_MARKER_OUT = 2
} D3D12_WRITEBUFFERIMMEDIATE_MODE
```

## 常量

| 常量                                             | 描述                                                                                                                                                                                                                             |
| ---------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| D3D12\_WRITEBUFFERIMMEDIATE\_MODE\_DEFAULT     | 写入操作的行为与常规复制写入操作相同。                                                                                                                                                                                                            |
| D3D12\_WRITEBUFFERIMMEDIATE\_MODE\_MARKER\_IN  | 保证写入操作在命令流中所有前面的命令（包括之前的 **WriteBufferImmediate** 操作）开始之后发生。                                                                                                                                                                   |
| D3D12\_WRITEBUFFERIMMEDIATE\_MODE\_MARKER\_OUT | 写入操作将被延迟，直到命令流中所有先前的命令（包括之前的 **WriteBufferImmediate** 操作）都已通过 GPU 管道完成。指定 **D3D12\_WRITEBUFFERIMMEDIATE\_MODE\_MARKER\_OUT** 的写入操作不会阻止后续操作开始。如果命令流中没有先前的操作，则写入操作的行为就像指定了 **D3D12\_WRITEBUFFERIMMEDIATE\_MODE\_MARKER\_IN** 一样。 |
