开发windows service程序例子

1. service程序

#include <windows.h>
#include <stdio.h>
#include <string.h>
#include <tchar.h>

       outputlog(_T("StartServiceCtrlDispatcher failed"));
       return GetLastError ();
    }

    outputlog("exit of main");
    return 0;
}

2. 编译，visual studio命令行

cl.exe -Femyservice.exe myservice.c advapi32.lib

3. 安装和启动service

sc create myservice binpath=c:\path\to\myservice.exe start=auto

sc start myservice
