如何获得网卡的硬件地址（MAC地址）？

Answer 1

PIP_ADAPTER_INFO pinfo = NULL;m_macaddress.Format("%02X:%02X:%02X:%02X:%02X:%02X",pinfo->Address[0],pinfo->Address[1],pinfo->Address[2],pinfo->Address[3],pinfo->Address[4],pinfo->Address[5]);

Answer 2

int WSAReturn;
char    Hostname[260];
char Hostaddress[20];
WSAReturn=WSAStartup( 0x0101, &WSAData );
if( WSAReturn == 0 ){
gethostname( Hostname, 260 );
struct hostent *pHostEnt;
pHostEnt = gethostbyname( Hostname);
if( pHostEnt != NULL ){
wsprintf( Hostaddress, "%d.%d.%d.%d",
( pHostEnt->h_addr_list[0][0] & 0x00ff ),
( pHostEnt->h_addr_list[0][1] & 0x00ff ),
( pHostEnt->h_addr_list[0][2] & 0x00ff ),
( pHostEnt->h_addr_list[0][3] & 0x00ff ) );
}
}
