# Thread::Join
|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
void Join()
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
等待线程结束并回收其资源。调用线程将被阻塞，直到目标线程完成执行。
|
|||
|
|
|
|||
|
|
**参数：** 无
|
|||
|
|
|
|||
|
|
**返回：** 无
|
|||
|
|
|
|||
|
|
**复杂度：** O(n)，n 为目标线程的执行时间
|
|||
|
|
|
|||
|
|
**注意：**
|
|||
|
|
- 如果线程已经被分离（Detach）或已经 Join 过，调用此方法将导致未定义行为。
|
|||
|
|
- 建议在使用完 Thread 对象后始终调用 Join 或 Detach。
|
|||
|
|

|
**示例：**
|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
Thread worker;
|
|||
|
|
worker.Start([]() {
|
|||
|
|
for (int i = 0; i < 5; ++i) {
|
|||
|
|
printf("Working...\n");
|
|||
|
|
Thread::Sleep(100);
|
|||
|
|
}
|
|||
|
|
}, "WorkerThread");
|
|||
|
|
|
|||
|
|
printf("Main thread waiting...\n");
|
|||
|
|
worker.Join();
|
|||
|
|
printf("Worker thread finished\n");
|
|||
|
|
```
