Hi,
 
Can anybody help me out to retrieve MAC address of my machine... using a C program....  I gave it a try using ioctl but not getting the correct result...... Following is my code......
 
int main()
{
......
struct ifr_req ifr ;
 
   strcpy(ifr.ifr_name, "rl0");
    if( ioctl(s, SIOCGIFADDR, &ifr) < 0 ) {
        cout << "Error" << endl ;
        return 0 ;
    }
 
    printf("ADDR(%s) = ") ;
        for(int i = 0; i < 6; i++) {
                printf("%x :", ifr.ifr_addr.sa_data[i] ) ;
        }
 

its not printing the correct result....
 
Thanks in advance
Dennis
