Re: [ros-dev] Command line

[Imre Leber]

The current design of defrag, chkdsk, recover FAT manipulation utilities in FreeDOS is
that there is a FAT manipulation library called the "FAT transformation engine"
that all the other utilities use. 

The big benefit of using this library is that it let's you write code to manipulate
the FAT file system  that works on FAT12, FAT16, FAT32 without knowing the exact FAT file
system this is going to run on. The same code works for FAT12, FAT16, FAT32 without having
code that looks like:

if it is FAT12 do this,
and if it is FAT16 do that 
and if it is FAT32 do again something else.

Like is done in the reactos loader (freeloader?)

This is optimized code that is used in real life programs.

Anyway this could be used as the basis for ufat.dll. The utilities that already use this
library could then also be put in here. And the rest can then be easily written.

What would then be needed is the actual functions that make up the interface to ufat.dll.

I've seen that there is example code on the internet that uses these functions. On
http://www.sysinternals.com/SourceCode/fmifs.html
