如果你使用的是Linux系統，則參考代碼如下：
#include <stdio.h>
#include <string.h>
#include <unistd.h>
#include <sys/ioctl.h>
#include <net/if.h>
#include "em9x60_drivers.h"
int GetLocalMac( char* mac )
{
int sock;
struct ifreq ifr_mac;
if( (sock=socket(AF_INET,SOCK_STREAM,0))<0 )
{
return -1;
}
memset( &ifr_mac, 0, sizeof(ifr_mac) );
strcpy( ifr_mac.ifr_name, "eth0" );
if( ioctl( sock, SIOCGIFHWADDR, &ifr_mac)<0 )
{
close( sock );
return -2;
}
memcpy( mac, ifr_mac.ifr_hwaddr.sa_data, 6 );
close( sock );
return 0;
}
int main( int argc,char* argv[] )
{
char BufStr[80];
char mac[6];
GetLocalMac( mac );
sprintf( BufStr, "Mac: x:x:x:x:x:x", (unsigned char)mac[0], (unsigned char)mac[1],
(unsigned char)mac[2], (unsigned char)mac[3],
(unsigned char)mac[4], (unsigned char)mac[5] );
printf( "Mac = %s\n", BufStr );
return 0;
}
