Are you sure you are passing a string? Or are you passing a number and expecting
a particulare result when you hexdump the file?

Why is this a problem? This is how things usually work on little endians
machines. If you are just reading and writing numbers in a binary way
this will work without a problem. However you may need to be carefull
when transferring the file to a bigendian machine.

So why do you perceive this swapping as a problem to be fixed?
