Question

WIndows编程 线程优先级问题，为什么运行结果不按优先级顺序？

#include<windows.h>
#include<iostream.h>

DWORD WINAPI ThreadIdle(LPVOID lpParam)
{

int i=0;
while(i++<10)
cout<<"Idle Thread is running"<<endl;
return 0;
}

DWORD WINAPI ThreadNormal(LPVOID lpParam)
{

int i=0;
while(i++<10)
cout<<"Normal Thread is running"<<endl;
return 0;
}

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

DWORD dwThreadID;
HANDLE h[2];

h[0] = ::CreateThread(NULL,0,ThreadIdle,NULL,CREATE_SUSPENDED,&dwThreadID);
::SetThreadPriority (h[0],THREAD_PRIORITY_IDLE);
::ResumeThread(h[0]);

h[1] = ::CreateThread(NULL,0,ThreadNormal,NULL,0,&dwThreadID);

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

::CloseHandle(h[0]);
::CloseHandle(h[1]);

return 0;
}

Answer 1

我也觉得是2个概念。。优先并不是先完成。。只是时间轮片的机会多一些而已。

Answer 2

结果优先跟线程是两个概念
