Question

c++用_beginthread创建一个线程的时候能获取他的句柄或者ID吗？

我想让它在执行完代码后自己挂起自己，并在需要的时候再恢复他

Answer 1

创建线程的时候就可以获得线程ID和句柄，你可以查查MSDN关于CWinThread的类成员

Answer 2

bool CMyOldWorkerThread::Run(int priority, DWORD dwThreadCreateFlags)
{
hThread = (HANDLE)_beginthreadex(NULL, 0, WorkerThreadProc, (LPVOID)this,
CREATE_SUSPENDED | (unsigned)dwThreadCreateFlags, (unsigned *)&dwThreadId);

if (hThread)
{
::SetThreadPriority(hThread, priority);

if (0 == (dwThreadCreateFlags & CREATE_SUSPENDED))
{
::ResumeThread(hThread);
}

return true;
}

return false;
}

google搜一下你的问题就出来了，how to a resume thread which was created by __beginthreadex

Answer 3

里面可以设立个循环，然后用信号量控制
