vc中如何得到本机网卡地址？

[xzou]

用到什么函数？

[net_worm]

先取得本机Hostname，然后由hostname取地址。

(一)得到MAC地址
CString GetLocalMacAdd()
{
CString sMacNumber;
sMacNumber = "unknowuser00";
ASTAT Adapter;
NCB Ncb;
UCHAR uRetCode;
//char NetName[50];
LANA_ENUM lenum;
int i;
memset( &Ncb, 0, sizeof(Ncb) );
Ncb.ncb_command = NCBENUM;
Ncb.ncb_buffer = (UCHAR *)&lenum;
Ncb.ncb_length = sizeof(lenum);
uRetCode = Netbios( &Ncb );
for(i=0; i < lenum.length ;i++)
{
memset( &Ncb, 0, sizeof(Ncb) );
Ncb.ncb_command = NCBRESET;
Ncb.ncb_lana_num = lenum.lana[i];
uRetCode = Netbios( &Ncb );
memset( &Ncb, 0, sizeof (Ncb) );
Ncb.ncb_command = NCBASTAT;
Ncb.ncb_lana_num = lenum.lana[i];
strcpy( (char *)Ncb.ncb_callname, "* " );
Ncb.ncb_buffer = (unsigned char *) &Adapter;
Ncb.ncb_length = sizeof(Adapter);
uRetCode = Netbios( &Ncb );
if ( uRetCode == 0 )
{
if (Adapter.adapt.adapter_address[0]+
Adapter.adapt.adapter_address[1]+
Adapter.adapt.adapter_address[2]+
Adapter.adapt.adapter_address[3]+
Adapter.adapt.adapter_address[4]+
Adapter.adapt.adapter_address[5]!=0)
{

sMacNumber.Format("%02x%02x%02x%02x%02x%02x",
Adapter.adapt.adapter_address[0],
Adapter.adapt.adapter_address[1],
Adapter.adapt.adapter_address[2],
Adapter.adapt.adapter_address[3],
Adapter.adapt.adapter_address[4],
Adapter.adapt.adapter_address[5] );
break;
}
}
}
return sMacNumber;
}
(二)得到IP地址:
int GetSelfIp(CString strIp[])
{
int nCount = 0;
WORD wversionrequested;
WSADATA wsadata;
char name[255];
wversionrequested = MAKEWORD( 2, 0 );
//调用WinSock2功能之前必须调用WSAStartup
if ( WSAStartup( wversionrequested, &wsadata ) == 0 )
{
if( gethostname ( name, sizeof(name)) == 0)
{
PHOSTENT hostinfo;
hostinfo = gethostbyname(name);
for(int i = 0; hostinfo!= NULL && hostinfo->h_addr_list[i] != NULL; i++ )
{
strIp[i] = inet_ntoa (*(struct in_addr *)hostinfo->h_addr_list[i]);
nCount++;
}
}
WSACleanup( );
}
return nCount;
}
