linux 枚舉網卡IP地址

#include <stdio.h>#include <sys/types.h>#include <ifaddrs.h>#include <netinet/in.h>#include <string.h>#include <arpa/inet.h>#include <vector>void getlocaliplist(std::vector<unsigned int>& ipList){struct ifaddrs* ifa = NULL, *oifa;if (getifaddrs(&ifa) < 0){return;}oifa = ifa;while (ifa != NULL){// IPv4 排除localhostif (ifa->ifa_addr != NULL && ifa->ifa_addr->sa_family == AF_INET && strncmp(ifa->ifa_name, "lo", 2) != 0){struct sockaddr_in* saddr = (struct sockaddr_in*)ifa->ifa_addr;unsigned int ip = ntohl(saddr->sin_addr.s_addr);ipList.push_back(ip);printf("ip: %u\n", ip);}ifa = ifa->ifa_next;}freeifaddrs(oifa);}int main(){std::vector<unsigned int> ipList;getlocaliplist(ipList);unsigned int ip = inet_addr("192.168.1.13");printf("inet_addr: %u\n", ip);return 0;}

這邊擷取的是整形表示,怎麼轉換成字串就不介紹了
