线程定义一般模式如下：
class CRawThread
{
private:
...
public:
...
friend unsigned __stdcall _raw_thread_function(void *param);
//将线程函数定义为这个类的友元函数，避免线程内部访问类的私有元素的时候出现错误。
};
unsigned __stdcall _raw_thread_function(void *param)
{
CRawThread *pThis = (CRawThread *)param; //这里将参数转换为原来的类型
IPHEADER *pip;
char buf[2048];
//------------------------------------------------------------------------
if(pThis->CreateSocket())
{
while(1)
{
if(WaitForSingleObject(pThis->m_hExitThread, 0) == WAIT_OBJECT_0)
{
ResetEvent(pThis->m_hExitThread);
goto EXIT_THREAD_0;
}
......
Sleep(30);
}
}
//------------------------------------------------------------------------
EXIT_THREAD_0:
pThis->CleanSocket();
SetEvent(pThis->m_hExitThreadOk);
_endthreadex(0);
return 0;
}
BOOL CRawThread::StartThread()
{
if(m_hThread == NULL){
//如果线程没有启动，启动线程
m_hThread = (HANDLE)_beginthreadex(
NULL,
0,
_raw_thread_function,
this, //这里传递参数
0,
&m_uThreadId);
return (m_hThread != NULL);
}
return TRUE;
}
