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：

 1 int _tmain(int argc, TCHAR* argv[])
 2 {
 3     SERVICE_TABLE_ENTRYW dispatch_table[] = {
 4         { gServiceName, (LPSERVICE_MAIN_FUNCTIONW)serviceMain },
 5         { NULL, NULL }
 6     };
 7
 8     if (!StartServiceCtrlDispatcherW(dispatch_table))
 9     {
10         svcReportEvent(TEXT("StartServiceCtrlDispatcherW Error!"));
11         gadgetLogWrite(NULL, "StartServiceCtrlDispatcherW Error!");
12     }
13 }

 1 void WINAPI serviceMain(DWORD argc, LPTSTR *argv)
 2 {
 3     gSvcStatusHandle = RegisterServiceCtrlHandlerW(gServiceName,
 4                                                    service_ctrl_handler);
 5
 6     if (IS_INVALID_HANDLE(gSvcStatusHandle))
 7     {
 8         gadgetLogWrite(NULL, "Failed to register Service Control for %S", gServiceName);
 9         return;
10     }
11 }

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
