C++线程优先级SetThreadPriority的使用实例

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：

// 
 
#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; 
}</div>
