多线程 （讨论，随便发表您的意见，^_^）

[远志999]

最近要写一个很烦的多线程方面的程序，在学校从来没有接触过，出来这几个月也没接触过，网上看了一些资料感觉还是无从下手啊，郁闷ing....

请各位大哥给小弟一点思路，最好举个小例子，^_^，那样我会更容易懂！

还有怎么处理好多线程，它们之间的挂起,启用， 以及对共享变量进行控制等等一些还请各位大哥帮小弟多说两句。

要是能做一个简单实例我就行了，哈。

支持!

m_pthread = (CThread*)
AfxBeginThread(RUNTIME_CLASS(CThread), THREAD_PRIORITY_NORMAL,
0, CREATE_SUSPENDED);
if(m_pthread)
{

m_pthread->ResumeThread();// run the thread
memcpy(&(m_pthread->m_cfg), &m_cfg, sizeof(m_cfg));
}
}

以后m_pthread->PostThreadMessage(WM_ALERT_THREADMSG, 0, (LPARAM)&m_alertask);//传入Thread中
用临界区做互斥

C R E AT E _ S U S P E N D E D，系统可以
完整地创建线程并对它进行初始化，但是要暂停该线程的运行，这样它就无法进行调度。
ResumeThread();// 开始执行

there are lots of code

PostThreadMessage想线程传替消息

[wkwhl]

m_hStop = ::CreateEvent(0, TRUE, FALSE, 0);
m_hPause = ::CreateEvent(0, TRUE, FALSE, 0);
m_hContinue = ::CreateEvent(0, TRUE, FALSE, 0);
g_eventKill = ::CreateEvent(0,TRUE, FALSE, 0);


while( ::WaitForSingleObject(m_hStop, 3) != WAIT_OBJECT_0 ) {
if(::WaitForSingleObject(m_hPause, 1) == WAIT_OBJECT_0) {
while(::WaitForSingleObject(m_hContinue, 50) != WAIT_OBJECT_0)
if(::WaitForSingleObject(m_hPause, 50) == WAIT_OBJECT_0)
::ResetEvent(m_hPause);
::ResetEvent(m_hContinue);
}

一点代码,我写的
别的我也帮不了
