c语言问题，不是很清楚

        }
    } else {

        strout = "Invalid token format!";
        return false;
    }
    return false;
}

这个里面有的函数不清楚，能不能说明一下！

抱歉，我确实没注意到， Daemon::IsDebug(); CRijndaelUtil::getDecryptedStr(token); 这两个是什么意思？ 头文件里面有 #include "daemon.H" #include "RijndaelHelper.h" 如果我自己查的话又该怎么处理！

VS IDE中，在不明白的符号上点鼠标右键，选转到定义。

“有的函数”是什么函数...

[归途醉染]

什么函数也不说....有的函数,请问是什么函数?
