�C�mo copiarias una estructura con esto campos?

struct hostent {
  char *h_name;                 Official name of host.
  char **h_aliases;             Alias list.
  int h_addrtype;               Host address type.
  int h_length;                 Length of address.
  char **h_addr_list;           List of addresses from name server.
}

�as�?

// Reserva de memoria para la estructura 
  ia->h = new hostent;
  
  // Copiamos el nombre
  ia->h->h_name = new char[strlen(tmp->h_name)+1];
  strcpy(ia->h->h_name, tmp->h_name);
  
  // Copiamos la lista de alias
  ptr = tmp->h_aliases;
  ia->h->h_aliases = new char*[16];
  while (*tmp->h_aliases) {
    *ia->h->h_aliases = new char[strlen(*tmp->h_aliases)+1];
    strcpy(*ia->h->h_aliases++, *tmp->h_aliases++);
  }
  // Copiamos el tipo de direcci�n
  ia->h->h_addrtype = tmp->h_addrtype;
  
  // Copiamos el tama�o de la direcci�n
  ia->h->h_length = tmp->h_length;
  
  // Copiamos la lista de direcciones
  ia->h->h_addr_list = new char*[1];
  ia->h->h_addr_list[0] = new char[strlen(tmp->h_addr_list[0])+1];
  strcpy(ia->h->h_addr_list[0], tmp->h_addr_list[0]);

�No habr�a una forma m�s f�cil?
