SYNOPSIS
        string query_ip_number(object  ob)
        string query_ip_number(mixed & ob)

DESCRIPTION
        Give the ip-number for the current user or the optional
        argument ob.

        If ob is given as reference (and it must be a valid object then),
        it will upon return be set to the struct sockaddr_in of the queried
        object, represented by an array of integers, one integer per
        address byte:
          ob[0.. 1]: sin_family
          ob[2.. 3]: sin_port
          ob[4.. 7]: sin_addr
          ob[8..15]: undefined.

HISTORY
        The return of the struct sockaddr_in was introduced in 3.2.1@81.
