在Windows开发中,经常用到多线程。
以下给出自己经常使用的方法。
在头文件中:
static unsigned int __stdcall ClientMonitoringThd(LPVOID lparam);
void DoMonitoringThd();
bool InitMonitoringThd();
//释放监视线程
bool UnInitMonitoringThd();
bool m_bMonitoringThdRunning;
HANDLE m_hMonitoringThd;
源文件中:
unsigned int __stdcall CSocketsClient::ClientMonitoringThd(LPVOID lparam)
{
CSocketsClient* pThis = reinterpret_cast<CSocketsClient*>(lparam);
pThis->DoMonitoringThd();
return 0;
}
bool CSocketsClient::InitMonitoringThd()
{
m_bMonitoringThdRunning = true;
unsigned int thd_id = 0;
m_hMonitoringThd = (HANDLE)::_beginthreadex(NULL, 0, ClientMonitoringThd, (LPVOID)this, 0, &thd_id);
return true;
}
void CSocketsClient::DoMonitoringThd()
{
SaveLog("DoMonitoringThd监视线程启动(进入while循环)");
while (m_bMonitoringThdRunning)
{
int i = 0;
Sleep(5);
}
SaveLog("DoMonitoringThd监视线程关闭(退出while循环)");
}
bool CSocketsClient::UnInitMonitoringThd()
{
m_bMonitoringThdRunning = false;
if (m_hMonitoringThd != INVALID_HANDLE_VALUE)
{
WaitForSingleObject(m_hMonitoringThd, INFINITE);
CloseHandle(m_hMonitoringThd);
m_hMonitoringThd = INVALID_HANDLE_VALUE;
}
return true;
}
注意初始化和释放资源。
