# RHIFence::Wait

```cpp
virtual void Wait(uint64_t value) = 0;
```

阻塞当前线程，直到围栏值达到或超过指定值。此方法用于 CPU 端等待 GPU 完成特定任务。

**参数：**
- `value` - 要等待的围栏值

**返回：** 无

**线程安全**：❌

**复杂度**：O(n)，具体取决于 GPU 完成指定值所需时间

**示例**：

```cpp
RHIFence* fence = device->CreateFence();

fence->Signal(500ULL);

// 执行其他 CPU 工作...

// 等待 GPU 完成到指定值
fence->Wait(500ULL);

// 继续后续处理
```
