Answer 2

CreateThread(NULL,0,Fun2Proc,NULL,0,NULL);
为什么这样写不应该是这样吗？
CreateThread(Fun2Proc,0,NULL,NULL,0,NULL);
第一个参数不应该是函数名称吗？

Answer 3

而CreateThread（）这个函数不是5个参数吗？

Answer 4

一个简单的例子~~===== MainFrm.h=====
...
private:
HANDLE threadhandle;
...
===== MainFrm.cpp =====
...
CMyThread::m_bRunning = true;  // run the thread
DWORD threadid;
threadhandle = CreateThread(NULL, 0, CMyThread::ThreadProc, this, 0, &threadid);
...
CMyThread::m_bRunning = false;  // stop the thread
WaitForSingleObject(threadhandle, 20000);  // timeout = 20s
...
===== MyThread.cpp =====
...
bool CMyThread::m_bRunning = false;// CMyThread
unsigned long WINAPI CMyThread::ThreadProc(void* p)
{
while (m_bRunning)
{
// do some loop
}
return 0;
}
