大家在多线程编程的时候，需要在程序退出之前，退出一些特定的后台线程。下面的代码可以完美解决此类问题。

#include <windows.h>
#include "stdio.h"

HANDLE hCheckThread, hCheckEvent;

unsigned long __stdcall HeatBeatUpdateThread(void * argList)
{
   int end =0, i = 0;

   end = GetTickCount();
   while (WaitForSingleObject(hCheckEvent, 1000000) != WAIT_OBJECT_0)
   {
      printf("count:%d, duration:%d/n", i, GetTickCount() - end);
      i++;
      end = GetTickCount();
   }
   printf("exit thread");
   return 0;
}

unsigned long BackgroundThreadCreate()
{
   unsigned long ThreadId = 0;

   // Create a manual-reset nonsignaled unnamed event
   hCheckEvent = CreateEvent(NULL, TRUE, FALSE, NULL);

   hCheckThread = CreateThread(NULL, 0, HeatBeatUpdateThread, NULL, 0, &ThreadId);

   return 0;
}

void main()
{

   int begin, end;
   BackgroundThreadCreate();

   Sleep(300);
   // Killed the check thread
   SetEvent(hCheckEvent); // signal thread to end
   begin = GetTickCount();

   // Wait max. 10 seconds for the firmware thread to terminate - if not, force a terminate
   if(WAIT_OBJECT_0 != WaitForSingleObject(hCheckThread,10000))
   {
      TerminateThread(hCheckThread,0);
   }

   end = GetTickCount() - begin;

   CloseHandle(hCheckEvent);
   CloseHandle(hCheckThread);

   while (1)
   {
      Sleep(10000000);
   }
}
