Пример из MSDN (см. Q118623) для локального NIC:



// The following code enumerates all LANA numbers, performs a reset (NCBREST),
// and an adapter status (NCBASTAT).

#include <windows.h>
#include <wincon.h>
#include <stdlib.h>
#include <stdio.h>
#include <time.h>

typedef struct _ASTAT_
{

ADAPTER_STATUS adapt;
NAME_BUFFER NameBuff [30];

}ASTAT, * PASTAT;

ASTAT Adapter;

void main (void)
{
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 );
printf( "The NCBENUM return code is: 0x%x \n", uRetCode );

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 );
printf( "The NCBRESET on LANA %d return code is: 0x%x \n",
lenum.lana[i], uRetCode );

memset( &Ncb, 0, sizeof (Ncb) );
Ncb.ncb_command = NCBASTAT;
Ncb.ncb_lana_num = lenum.lana[i];

strcpy( Ncb.ncb_callname, "* " );
Ncb.ncb_buffer = (char *) &Adapter;
Ncb.ncb_length = sizeof(Adapter);

uRetCode = Netbios( &Ncb );
printf( "The NCBASTAT on LANA %d return code is: 0x%x \n",
lenum.lana[i], uRetCode );
if ( uRetCode == 0 )
{
printf( "The Ethernet Number on LANA %d is:
%02x%02x%02x%02x%02x%02x\n",
lenum.lana[i],
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] );
}
}
