     htonl, htons, ntohl, ntohs - convert values between host and
     network byte order

     These routines convert 16 and 32 bit quantities between net-
     work byte order and host byte order.  On machines such as
     the SUN these routines are defined as null macros in the
     include file <_n_e_t_i_n_e_t/_i_n._h>.

     These routines are most often used in conjunction with
     Internet addresses and ports as returned by
     _g_e_t_h_o_s_t_b_y_n_a_m_e(3N) and _g_e_t_s_e_r_v_e_n_t(3N).

BBUUGGSS
     The VAX handles bytes backwards from most everyone else in
     the world.  This is not expected to be fixed in the near
     future.
