如何知道线程处于挂起状态

Question

I am suspending a thread using an event. When the eventSuspend is signaled the thread waits on it.

// inside the thread function
WaitForSingleObject(eventSuspend, INFINITE );

Now from outside I set it to wait by eventSuspend.ResetEvent() but loop inside the thread function is kind of long (time consuming). How can I know that the thread has finished whatever it was doing and now it is indeed waiting on this signal?

Answer 1

Your question is wrong: A thread that is waiting is not suspended!

A thread is suspended after calling SuspendThread() but not after calling WaitForSingleObject() .

Simply set a BOOL flag when the thread loop starts and reset the flag when the thread loop exits then you know if it runs or not.

If you want futher informations about a thread, like if it is supended or not, you can use the code that I posted here: How to get thread state (eg suspended), memory + CPU usage, start time, priority, etc
