本程序用户获取主机的IP地址和MAC地址，头文件与函数原型如下



#include "getIP.h"

int get_ip(char *ipaddr, char *netmask, const char *ethname)



#include "getIP.h"

int get_mac(char *mac)





以下是get_ip函数简单使用范例



//定义IP和MAC所需要的存储空间

char ethname[] = "eth0"

char ipaddr[20] 　　　　//IP地址最长为16个字符

char netmask[20] 　　　　//子网掩码最长为18个字符



//获取IP地址

get_ip(ipaddr,netmask,ethname)



//输出结果

printf(" s\n",ipaddr)

printf(" s\n",netmask)





以下是get_mac函数简单使用范例

-The program user access to the host' s IP address and MAC address, the following function prototype header file# include " getIP.h"　int get_ip (char* ipaddr, char* netmask, const char* ethname) # include " getIP.h"　int get_mac (char* mac)　use the following simple example is get_ip function// define the IP and MAC need storage space char ethname [] = " eth0"　 char ipaddr [20] // IP address of up to 16 characters char netmask [20] // mask for up to 18 characters// Obtain an IP address get_ip (ipaddr, netmask, ethname) // output printf ("　 s \ n" , ipaddr)　printf ( "　 s \ n" , netmask)　use the following simple example is get_mac function
