hi

In my Linux C++ application I'm using getpeername in order to get the peer IP. my problem is: when I enable the IPv6 on my machine the IP I got from the peer is with family IF_INET6 although it is IPv4.

code:

int GetSockPeerIP( int sock)
{
     struct sockaddr_storage ss;
     struct socklen_t salen = sizeof(ss);
     struct sockaddr *sa;
     memset(&ss,0,salen);
     sa = (sockaddr *)&ss;

     if(getpeername(sock,sa,&salen) != 0)
     {
        return -1;
     }

     char * ip=NULL:
     if(sa->sa_family == AF_INET)
     {
        ip = inet_ntoa((struct sockaddr_in *)sa)->sin_addr);
     }
     else
     {
         //ip = how to convert IPv6 to char IP?
     }

     return 0;
}

how can I fix it?

thanks1
