如何判断一个Win32线程终止？

How can I determine if a Win32 thread has terminated?

对于 GetExit codeThread <文档/ STRONG>警告不要使用它因为这个原因，因为错误code STILL_ACTIVE可以因其他原因被退回。

The documentation for GetExitCodeThread warns to not to use it for this reason since the error code STILL_ACTIVE can be returned for other reasons.

推荐答案

MSDN提到，当一个线程终止，线程对象达到一个信号状态，满足了等待的对象，任何线程。

MSDN mentions that "When a thread terminates, the thread object attains a signaled state, satisfying any threads that were waiting on the object".

所以，你可以检查一个线程是否已经通过检查线程处理的状态终止 - 无论是信号还是不：

So, you can check for whether a thread has terminated by checking the state of the thread handle - whether it's signaled or not:

DWORD result = WaitForSingleObject( hThread, 0);

if (result == WAIT_OBJECT_0) {
    // the thread handle is signaled - the thread has terminated
}
else {
    // the thread handle is not signaled - the thread is still alive
}
