本文实例讲述了C++线程优先级SetThreadPriority的使用方法，分享给大家供大家参考。具体方法如下：

复制代码 代码如下:// ThreadPriority.cpp : 定义控制台应用程序的入口点。

//

#include "stdafx.h"

#include <Windows.h>

DWORD WINAPI ThreadProcIdle(LPVOID lpParameter)

{

for (int i=0;i<20;i++)

{

printf("I'm in thread IDLE...n");

}

return 0;

}

DWORD WINAPI ThreadProcNormal(LPVOID lpParameter)

{

for (int i=0;i<20;i++)

{

printf("I'm in thread Normal...n");

}

return 0;

}

int _tmain(int argc, _TCHAR* argv[])

{

DWORD dwThreadIdIdle;

DWORD dwThreadIdNormal;

HANDLE hThread[2];

//开启两个线程

hThread[0] = ::CreateThread(NULL,0, ThreadProcIdle, NULL, CREATE_SUSPENDED, &dwThreadIdIdle);

::SetThreadPriority(hThread[0],THREAD_PRIORITY_IDLE);

::ResumeThread(hThread[0]);

hThread[1] = ::CreateThread(NULL,0, ThreadProcNormal, NULL, CREATE_SUSPENDED, &dwThreadIdNormal);

::SetThreadPriority(hThread[1],THREAD_PRIORITY_NORMAL);

::ResumeThread(hThread[1]);

//等待两个线程结束

::WaitForMultipleObjects(2,hThread,TRUE,INFINITE);

::CloseHandle(hThread[0]);

::CloseHandle(hThread[1]);

return 0;

}

希望本文所述对大家的C++程序设计有所帮助。
