  DESCRIPTION
<      These routines convert 16-bit and 32-bit quantities  between
--
>      These routines convert 16-bit, 32-bit and 64-bit quantities
       between network  byte  order  and host byte order. On some
       architectures these routines are defined as NULL macros in the
       include  file  <netinet/in.h>.  On  other architectures, the
       routines are functional when the host  byte  order  is  dif-
       ferent from network byte order.
  
  
       The routines are most often used in conjunction with  Inter-
       net addresses and ports as returned by gethostent() and get-
       servent().        See        gethostbyname(3NSL)         and
       getservbyname(3SOCKET).
