Macos Mac osx启动守护程序和套接字

我有一个osx守护进程，它监听端口8080

我的plist文件：com.mycompany.daemon.plist

我的问题出现在这里，当我试图通过launch_msg（）签入时，我得到了“不允许操作”错误。我试图以root用户身份启动我的守护进程，但没有成功。这是一个好方法吗？有没有其他方法可以打开插座？我正在使用osx 10.9.2。谢谢

if ((checkin_request = launch_data_new_string(LAUNCH_KEY_CHECKIN)) == NULL) {
    retval = EXIT_FAILURE;
    goto done;
}

if ((checkin_response = launch_msg(checkin_request)) == NULL) {
    asl_log(asl, log_msg, ASL_LEVEL_ERR, "launch_msg(\"" LAUNCH_KEY_CHECKIN "\") IPC failure: %m");
    retval = EXIT_FAILURE;
    goto done;
}
