Win32多线程之线程挂起**结束

这部分介绍线程“三态转换”的函数，创造，挂起，**，结束

#include "stdafx.h"

#include <windows.h>

#include <iostream>

using namespace std;



DWORD WINAPI FunOne(LPVOID param)

{

       int num1 = 0;

       while (true)

       {

               Sleep(1000);

               cout << "thread1 num "<<num1++<<endl;

       }

       return 0;

}



DWORD WINAPI FunTwo(LPVOID param)

{

       int num2 = 100;

       while (true)

       {

               Sleep(1000);

               cout << "thread2 num " << num2-- << endl;

       }

       return 0;

}



int main(int argc, char* argv[])

{

       int input = 0;

       //HANDLE hand1 = CreateThread(NULL, 0, FunOne, (void*)&input, CREATE_SUSPENDED, 
NULL);

       //HANDLE hand2 = CreateThread(NULL, 0, FunTwo, (void*)&input, CREATE_SUSPENDED, 
NULL);



       HANDLE hand1 = CreateThread(NULL, 0, FunOne, NULL, CREATE_SUSPENDED, NULL);

       HANDLE hand2 = CreateThread( NULL, 0, FunTwo, NULL, CREATE_SUSPENDED, NULL);

       //第四个参数表示线程初始状态为挂起状态

       while (true)

       {

               cin >> input;

               if (input == 1)

               {

                      ResumeThread(hand1);//**线程

                      ResumeThread(hand2);

               }

               else

               {

                      SuspendThread(hand1);//挂起线程

                      SuspendThread(hand2);

               }

       }

       TerminateThread(hand1, 1);//结束线程

       TerminateThread(hand2, 1);

       return 0;

}

运行结果

• 主线程接收到1，**两个线程。两个线程以1000时间间隔，一个从0正数，一个从100倒计时。直到我输入任意其他字符，两个线程被挂起。

• 注意到：输出有“混乱情况”，这是由于每个线程都是多个输出语句，并且没有被定义为一个不可分割的整体的“事务”，所以会有两个线程输出操作交替执行，出现像第一行输出那样的情况
