獲取網管或路由器的mac值?

請教各位大俠,如何像vc中的sendarp()函數,輸入連到電腦上的網管或路由器的ip就可以返回mac值?謝謝!

自己声明sendarp

WinSock;Function sendarp(ipaddr:ulong;
temp:dword;
ulmacaddr:pointer;
ulmacaddrleng:pointer) : DWord; StdCall; External 'Iphlpapi.dll' Name 'SendARP';procedure TForm1.Button1Click(Sender: TObject);
var
myip:ulong;
mymac:array[0..5] of byte;
mymaclength:ulong;
r:integer;
begin
myip:=inet_addr(PChar('192.168.6.180'));
mymaclength:=length(mymac);
r:=sendarp(myip,0,@mymac,@mymaclength);
label1.caption:='errorcode:'+inttostr(r);
label2.caption:=format('%2.2x:%2.2x:%2.2x:%2.2x:%2.2x:%2.2x',[mymac[0],mymac[1],mymac[2],mymac[3],mymac[4],mymac[5]]);
end;
