You may either use ifconfig or the following piece of code
(exchange "eth0" for the device in use):

--cut--
#include <sys/socket.h>
#include <sys/ioctl.h>
#include <netinet/in.h>
#include <net/if.h>
#include <stdio.h>

int main(int argc, char **argv) {

struct ifreq myifr;
struct hostent *h;
int i;
char *dot;

sprintf(myifr.ifr_ifrn.ifrn_name,"%s", "eth0");

/* get IP address and write to nameip */
ioctl(socket(AF_INET, SOCK_DGRAM, IPPROTO_IP), SIOCGIFADDR, &myifr);

dot="";
for(i=0; i<4;i++) {
printf("%s%d", dot,
(unsigned char) myifr.ifr_ifru.ifru_addr.sa_data[2+i]);
dot=".";
}
printf("\n");
return(0);
}
--cut--

A MAC-Address query is very simular
