       little-endian data to the host's endianness and from the host's to
       little-endian respectively.
  
       These functions are not standardized and the header they appear in varies
       between the BSDs and GNU/Linux.  Applications that wish to be portable,
!      shoulda instead use the byteorder(3C) functions.
  
       All of these functions in both families simply return their input when
       the host's native byte order is the same as the desired order.  For
       example, when calling htonl(3C) on a big-endian system the original data
       is returned with no conversion or modification.
