It's not a good idea to just dump memory structures out to a disk file, 
because that kind of code is highly non-portable. Instead of using
functions like fwrite() and fread(), write routines that will output
just a single 16 or 32 bit value (using shifts and binary operators to 
split things up into a series of bytes that can be written out with
a function like putc()), and change your file saving code to write
each field individually using these helper functions. That way your 
routines will work correctly on any compiler or platform.
