virtual uint64_t GetCompletedValue() const = 0;
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
获取围栏已完成的最大值。该值表示 GPU 已完成的所有信号操作中的最高值。
|

**参数：** 无

**示例**：
|

|
|
```cpp
|
|||
|
|
RHIFence* fence = device->CreateFence();
|
|||
|
|
|
|||
|
|
fence->Signal(100ULL);
|
|||
|
|
|
|||
|
|
uint64_t completed = fence->GetCompletedValue();
|
|||
|
|
// completed >= 100 表示 GPU 已完成该信号
|
|||
|
|
|
|||
|
|
if (completed >= 100) {
|
|||
|
|
// GPU 已完成 100 之前的所有工作
|
|||
|
