Subject: Extra functions/datatypes for external mode?

Hi,

I currently have some C code that emulates a random password generator,
which I was looking at porting to a john external mode.

While most of the code works as 32-bit signed integers, I need to do the
cast as double, then multiply by (1.0/2^32) trick, which I'm not really
sure how to do in integer-only arithmatic (I'm guessing it's technically
possible).

Is there a way to define C functions that external mode can call, or just
add more data types to external mode?

Thanks,
  Michael
