    I re-read my 3.4R FreeBSD manual pages and the functions appeared
    in 4.2BSD. The manual pages only state that the database files
    (e.g. /etc/services) will stay open when setservent() was called
    with a non-zero argument. They _do_not_ state that you
    have to open the databse with setservent() when
    using getservbyname().

    According to the GNU C Library Reference Manual (2.00 beta)
    one should use setservent() / endservent() when querying the
    Services Database with getservent().
    There is no reason to call the two functions when
    using getservbyname() to retrieve records. Also Stevens in
    his book 'UNIX Network Programming' didn't use the two
    functions to surround getservbyname().
