C++ 编写Windows service

最近实现一个windows server端守护进程启动服务功能（c++实现），遇到了一些问题，记录一下

1. 启动Service实现代码：

 int _tmain(int argc, TCHAR* argv[])
 {
     SERVICE_TABLE_ENTRYW dispatch_table[] = {
         { gServiceName, (LPSERVICE_MAIN_FUNCTIONW)serviceMain },
         { NULL, NULL }
     };

     if (!StartServiceCtrlDispatcherW(dispatch_table))
     {
         svcReportEvent(TEXT("StartServiceCtrlDispatcherW Error!"));
         gadgetLogWrite(NULL, "StartServiceCtrlDispatcherW Error!");
     }
 }

 void WINAPI serviceMain(DWORD argc, LPTSTR *argv)
 {
     gSvcStatusHandle = RegisterServiceCtrlHandlerW(gServiceName,
                                                    service_ctrl_handler);

     if (IS_INVALID_HANDLE(gSvcStatusHandle))
     {
         gadgetLogWrite(NULL, "Failed to register Service Control for %S", gServiceName);
         return;
     }
 }

需要注意的是本地调试的时候，是无法获得ServiceCtrlHandler，必须要在系统服务里直接调用，所以测试打印一定要做好
