SetThreadPriority的使用

// 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;}
