The gethostent() function reads the next entry of the hosts
    database file (TCPIP$ETC:IPNODES.DAT).
    See the NETDB.H header file for a description of the hostent
    structure.
    The gethostent() function uses a common static area for its
    return values. Therefore, subsequent calls to gethostent()
    overwrite any existing host entry. You must make a copy of the
    host entry, if you wish to save it.
