# Thread::Yield
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
static void Yield()
|
||
|
|
```
|
||
|
|
|
||
|
|
让出当前线程的时间片，允许操作系统调度器将 CPU 时间分配给其他就绪线程。
|
||
|
|
|
||
|
|
**参数：** 无
|
||
|
|
|
||
|
|
**返回：** 无
|
||
|
|
|
||
|
|
**复杂度：** O(1)
|
||
|
|
|
||
|
|
**使用场景：**
|
||
|
|
- 在自旋等待某个条件时调用，避免浪费 CPU 周期。
|
||
|
|
- 在长时间循环中定期让出时间片，提高其他线程的响应性。
|
||
|
|
|
||
|
|
**示例：**
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
volatile bool ready = false;
|
||
|
|
|
||
|
|
Thread worker;
|
||
|
|
worker.Start([]() {
|
||
|
|
ready = true;
|
||
|
|
}, "WorkerThread");
|
||
|
|
|
||
|
|
// 忙等待，但定期让出时间片
|
||
|
|
while (!ready) {
|
||
|
|
Thread::Yield();
|
||
|
|
}
|
||
|
|
|
||
|
|
worker.Join();
|
||
|
|
```
