注:
執行方式如(假設編譯出的執行文件為getmac):
./getmac /dev/net0
MDI(MAC Driver Interface)
MACIOC_GETADDR
向MDI driver發出請求從而獲取網卡當前MAC地址 (the current MAC address);
MACIOC_GETRADDR
向MDI driver發出請求從而獲取網卡廠商MAC地址(the factory MAC address);
此程序適用於SCO OpenServer和UnixWare,在OpenServer 5.06上測試通過。
我在嘗試使用MACIOC_GETRADDR時提示無效參數,我估計也許是與驅動中沒有提供相應的實現有關,因為我在偶然看到的注釋版權信息為
/*

的AT-2500TX驅動源碼中,相應部分只包含了MACIOC_GETADDR的實現,而沒有MACIOC_GETRADDR。
