使用ACE获取主机的IP地址,不知道为什么会有127.0.0.1?
#include "stdafx.h"
#include "ace\OS.h"
#include "ace\SOCK_Connector.h" //用ACE获取本机IP address
int _tmain(int argc, _TCHAR* argv[])
{
WSADATA wsaData;
if (WSAStartup(MAKEWORD(2,2),&wsaData) != 0) return 0; //得到主机名
char hostname[MAXHOSTNAMELEN];
ACE_OS::hostname(hostname, sizeof (hostname));
printf("host name is %s\n", hostname);
printf("--------------------------\n"); ACE_INET_Addr* addr_array1;
size_t count = 0;
if (ACE::get_ip_interfaces(count, addr_array1) != 0)
{
return 0;
} //可以装下IPv6地址(46),IPv4为INET_ADDRSTRLEN(16)
char address[INET6_ADDRSTRLEN];
//为了最后要删除空间,所以定义新的变量
ACE_INET_Addr* addr_array2 = addr_array1;
for(size_t i=0; i<count; i++)
{
unsigned int net_order_ip = htonl(addr_array2->get_ip_address());
struct in_addr *paddr_stru = (in_addr*)&net_order_ip;
printf("format 0: %s\n", ACE_OS::inet_ntoa(*paddr_stru)); addr_array2->addr_to_string(address, sizeof (address), 1);
printf("format 1: %s\n", address);
addr_array2++;
printf("--------------------------\n"); } //记得要delete[] addr_array;
delete[] addr_array1; getchar();
return 0;
}
