Is there any library function to determine the mac address of my own network
adapter.

I assume you know ‘netinfo -l’ under QNX - call it from “system(
“netinfo -l > into_a_file” )” and write a parser for it. should be the
simplest way :slight_smile:

take a look at ftp.qnx.com/usr/free/qnx4/os/net/netraw.v4.tgz there’s an
example inside that enumerates network interfaces and displays NICs
information for each including MAC address etc.

void main()

printf (“Could not attach to Net (%d)\n”, errno);
exit(0);
}

memset(&rnodemap, 0, sizeof(rnodemap));
rnodemap.type=_NET_RNODEMAP;
rnodemap.log_nid=getnid();

rnodemap_reply=(struct _net_rnodemap_reply *) data;

if ((Send(pid, &rnodemap, rnodemap_reply, sizeof(rnodemap),
1000))==-1) {
printf (“Send error\n” );
exit(0);
}

printf (“MAC: “); // If you have multiple cards you will need a loop here
for (ctr=0; ctr<6; ctr++)
printf (”%02X”, rnodemap_reply->card[0].phys_addr[ctr]);

printf ("\n");

}

The sys/net* headers are in the netraw package on /usr/free.

I think all the relevant bits are:

#define _NET_RNODEMAP 0x421

struct _net_rnodemap {
short unsigned int type;
short unsigned int subtype;
nid_t log_nid;
short unsigned int zero1;
short unsigned int zero2;
};
struct _card_info {
short unsigned int lan_addr;
unsigned char phys_addr[6];
time_t last_tx_fail;
};
struct _net_rnodemap_reply {
short unsigned int status;
short unsigned int zero1;
short unsigned int num_card;
short unsigned int zero2;
struct _card_info card[];
};

There is a message that can be sent to Net.* drivers that returns the
information that ‘netinfo -l’ displays.

Someone from QSSL with have to give you the info on how to send that
message. I think there was a non-disclosure agreement to sign.
