Hi,
I decided to write a new fdisk(8) program for unix. The main goal was to be
able to do all the MBR manipulation from the command line, to be portable
across all unix platform using libc, to work alone, to be as small and
simple as possible and to be easy to maintain and extend.
I did it.
Program:
- do anything the exiting fdisk(8) do and even more(also more to come).
- compiles, run and work on any sane unix platform with standard libc.
- has no need for anything else than "/bin/sh" and "/usr/lib/libc*".
- is 10 times smaller.
- in pure C.
- has no struct.
I tested it, but you know I might have forget some details or even do
things better.
Please review the code, the structure, the functionality and the error
possibility.
I accept any (good and/or bad) feedback if its constructive.
Thanks for taking the time to do so and if you don't thanks anyway...
