getifaddrs()和struct ifaddrs的使用,获取本机IP ifaddrs结构体定义如下: C代码 struct ifaddrs { struct ifaddrs *ifa_next; /* Next item in list */ char *ifa_name; /* Name of interface */ unsigned int ifa_flags; /* Flags from SIOCGIFFLAGS */ struc
使用函数getifaddrs来枚举网卡IP,其中使用到的结构体如下所示: struct ifaddrs { struct ifaddrs *ifa_next; /* Next item in list */ char *ifa_name; /* Name of interface */ unsigned int ifa_flags; /* Flags from SIOCGIFFLAGS */ struct sockaddr *ifa_addr; /* Address of interface *
