用vs2012编写c程序，如何获得CPU ID、MAC地址和硬盘序列号

Posted 2023-03-13

参考技术A 读mac地址:
int get_mac_addr(int* pintrface,char *str_mac_addr)

int fd, retn = 0;
int intrface; /* int intrface */
struct ifreq buf[MAXINTERFACES];
struct arpreq arp;
struct ifconf ifc;

char mac_addr_max[MAC_ADDR_LEN];
char mac_addr_tmp[MAC_ADDR_LEN];

if ((fd = socket (AF_INET, SOCK_DGRAM, 0)) >= 0)

memset(mac_addr_max,0,sizeof(mac_addr_max));
memset(mac_addr_tmp,0,sizeof(mac_addr_tmp));
ifc.ifc_len = sizeof buf;
ifc.ifc_buf = (caddr_t) buf;
if (!ioctl(fd, SIOCGIFCONF, (char *) &ifc))

intrface = ifc.ifc_len / sizeof (struct ifreq);
*pintrface = intrface;
dprintf(("interface num is intrface=%d\n\n",intrface));
while (intrface-- > 0)

dprintf (("net device %s\n", buf[intrface].ifr_name));
arp.arp_pa.sa_family = AF_INET;
arp.arp_ha.sa_family = AF_INET;
((struct sockaddr_in*)&arp.arp_pa)->sin_addr.s_addr =
((struct sockaddr_in*)(&buf[intrface].ifr_addr))->sin_addr.s_addr;
if (!(ioctl (fd, SIOCGARP, (char *) &arp)))

memset(mac_addr_tmp,0,sizeof(mac_addr_tmp));
sprintf(mac_addr_tmp,"%02x%02x%02x%02x%02x%02x",
(unsigned char)arp.arp_ha.sa_data[0],
(unsigned char)arp.arp_ha.sa_data[1],
(unsigned char)arp.arp_ha.sa_data[2],
(unsigned char)arp.arp_ha.sa_data[3],
(unsigned char)arp.arp_ha.sa_data[4],
(unsigned char)arp.arp_ha.sa_data[5]);

if( strcmp(mac_addr_max,mac_addr_tmp)<0 )

memset(mac_addr_max,0,sizeof(mac_addr_max));
strcpy(mac_addr_max,mac_addr_tmp);

//End of if(!(ioctl(fd,SIOCGARP,(char*) &arp)))
else

dprintf (("cpm: ioctl device %s\n", buf[intrface].ifr_name));

//End of while (intrface-- > 0)
//End of if (!ioctl (fd, SIOCGIFCONF, (char *) &ifc))
else

//perror ("cpm: ioctl");


//End of if ((fd = socket (AF_INET, SOCK_DGRAM, 0)) >= 0)
else

//perror ("cpm: socket");

close (fd);

strcpy(str_mac_addr,mac_addr_max);
return retn;
追问

谢谢你啊，我需要完整的代码，比如需要什么头文件，这个好多数据类型都没有定义
