getting the MacId

can anyone of you give me a hint on how to read the MacId(s) of my network adpter(s)???

On what OS/Compiler? The following works on MSVC6

Code:

---

#include "stdafx.h"


// Obtain the Media Access Control Address (MAC)
// needs netapi32.lib
 
#include <windows.h>
#include <nb30.h>
#include <stdio.h>
#include <tchar.h>
 
typedef struct _ASTAT_
{
    ADAPTER_STATUS adapt;
    NAME_BUFFER    NameBuff [30];
}ASTAT, * PASTAT;
 
ASTAT Adapter;
 
int _tmain(int argc, _TCHAR* argv[])
{
    NCB ncb;
    BYTE bRetCode;
 
    memset( &ncb, 0, sizeof(ncb) );
    ncb.ncb_command = NCBRESET;
    ncb.ncb_lana_num = 0;
 
    bRetCode = Netbios( &ncb );
    _tprintf( _T("The NCBRESET return code is: 0x%x \n"), bRetCode );
 
    memset( &ncb, 0, sizeof(ncb) );
    ncb.ncb_command = NCBASTAT;
    ncb.ncb_lana_num = 0;
 
    // Must be in non-unicode
    strcpy( (char*) ncb.ncb_callname,  "*              " );
    ncb.ncb_buffer = (unsigned char *) &Adapter;
    ncb.ncb_length = sizeof(Adapter);
 
    bRetCode = Netbios( &ncb );
    _tprintf( _T("The NCBASTAT return code is: 0x%x \n"), bRetCode );
    if ( bRetCode == 0 )
    {
        _tprintf( _T("The MAC Address is: %02x%02x%02x%02x%02x%02x\n"),
                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] );
    }
    return 0;
}
