How to get Network Adapter MAC Address by calling C's API

[曾暘展]

I don't know how to get the MAC Address by calling C's API.
I had read the API Document, but I still cannot find the functions that I can use.
Please help me. Thanks a lot.

Hi,

this code is from the comp.sys.hp.hpux newsgroup FAQ. I haven't tested it (no compiler!) :

#include
#include
#include

main(argc, argv)
int argc;
char *argv[];
{
struct fis s_fis;
struct fis s_fis;
int lanic;
char *ascii[6];

if (argc < 2) {
printf ("Usage: %s \n", argv[0]);
exit (1);
}

lanic = open(argv[1], O_RDWR);
if (lanic < 0) {
perror("Error in opening %s", argv[1]);
printf("Error = %d\n", lanic);
exit(1);
} else {
s_fis.reqtype = LOCAL_ADDRESS;
s_fis.vtype = INTEGERTYPE;

ioctl(lanic, NETSTAT, &s_fis);
net_ntoa(ascii, s_fis.value.s, 6);
printf("Station address of %s is %s\n", argv[1], ascii);

s_fis.reqtype = PERMANENT_ADDRESS;
s_fis.vtype = INTEGERTYPE;
ioctl(lanic, NETSTAT, &s_fis);
net_ntoa(ascii, s_fis.value.s, 6);
printf("Permanent Station address of %s is %s\n", argv[1], ascii);
close(lanic);
}
}
