MSDN:

The following sample code demonstrates how you can use the thread
handle returned by _beginthreadex
with the synchronization API
WaitForSingleObject. The
main thread waits for the second thread to terminate before it continues. When
the second thread calls _endthreadex
, it causes its thread object to go
to the signaled state. This allows the primary thread to continue running. This
cannot be done with _beginthread
and _endthread
, because
_endthread
calls CloseHandle
, destroying the thread object before
it can be set to the signaled state.

示例代码：

#include "stdafx.h"
#include "windows.h"
#include "process.h"
#include <iostream>
using namespace std;

unsigned _stdcall ThreadDo(void*)
{
    int nSum = 0;
    for(int i=0; i<100; ++i)
    {
        cout<<"the number is "<<i<<endl;
        nSum+=i;
    }
    _endthreadex(0);
    return 0;
}

int _tmain(int argc, _TCHAR* argv[])
{
    unsigned threadID;
    HANDLE hThread = (HANDLE)_beginthreadex(NULL, 0, ThreadDo, NULL, CREATE_SUSPENDED, &threadID);
    ResumeThread(hThread);
    WaitForSingleObject(hThread, INFINITE);//让主线程阻塞

    cout<<"main thread get running"<<endl;
    CloseHandle(hThread);

    return 0;
}
