c - servicemain 函数仅在服务事件停止时启动

Question

我使用了以下链接http://www.muukka.net/programming/service/Beeper%20Service.cpp编写一个服务。但这里的问题是，只有当请求服务停止时，servicemain 函数才会被调用。

我想预先启动servicemain函数，以检测连接的USB设备..我应该做什么..

Answer 1

在代码中:

SC_HANDLE service = CreateService( serviceControlManager, serviceName, serviceName, SERVICE_ALL_ACCESS, SERVICE_WIN32_OWN_PROCESS, SERVICE_AUTO_START, SERVICE_ERROR_IGNORE, path, 0, 0, 0, 0, 0 );

更改为:

SC_HANDLE service = CreateService( serviceControlManager, serviceName, serviceName, SERVICE_ALL_ACCESS, SERVICE_WIN32_OWN_PROCESS, SERVICE_DEMAND_START, SERVICE_ERROR_IGNORE, path, 0, 0, 0, 0, 0 );
