                     28: .SH DESCRIPTION
                     29: These routines convert 16 and 32 bit quantities between network
                     30: byte order and host byte order.  On machines such as the SUN
                     31: these routines are defined as null macros in the include file
                     32: .RI < netinet/in.h >.
                     33: .PP
                     34: These routines are most often used in conjunction with Internet
                     35: addresses and ports as returned by
                     36: .IR gethostbyname (3N)
                     37: and
                     38: .IR getservent (3N).
                     39: .SH "SEE ALSO"
                     40: gethostbyname(3N),
                     41: getservent(3N)
                     42: .SH BUGS
                     43: The VAX handles bytes backwards from most everyone else in
                     44: the world.  This is not expected to be fixed in the near future.
