Hope this helps.

struct hostent *he;
struct sockaddr_in sin;
char *hostname=3D"freebsd.org";
int port=3D80;

  sin.sin_family =3D AF_INET;
  sin.sin_port =3D htons(port);
  sin.sin_addr.s_addr =3D inet_addr(hstname);
  if(sin.sin_addr.s_addr =3D=3D INADDR_NONE) {
    he =3D gethostbyname(hstname);
    if(!he) {
      close(s);
      errno=3D0;
      return -1;
      }
    memcpy(&sin.sin_addr, he->h_addr, he->h_length);
    }
