The most straight-forward way was when reading and writiing integers, floats
etc process them a character at a time.

another way is to make a function that reverses the bytes in the number
and use that before writing and after reading...

Then you arrange things so that when the edianness of the data file
matches that of the CPU that then the byte-shuffle routine doesn't
run.

there's two ways to do that too.

   One is to always use the same endian-ness in the data file and if
   compiling on correctly endian hardware #define an empty macro to
   leave the bytes alone

   some environments (eg POSIX) provide htonl() etc which does this for
   you.

   The other is to have the software detect the endianness of the data
   file and set a flag which youv'e implemented to switch the
   byte-swapping on or off at runtime.
