Who maintains the imagehlp dll?

[Andrew de Quincey]

Now that I have IDA nearly sorted, I was wondering.. who maintains the 
imagehlp dll? It seems kinda empty, and I'm sure it was at one point more 
complete (I looked into wine some time ago).

I ask this because about a year or so ago I got about 3/4 of the way through 
reverse engineering the Windows PDB formats (up to those supported by 
VS.NET). If I had an actual implementation goal in mind and feedback from 
people using it, I might actually be bothered to finish it off....

Incidentally, I have years of reverse engineering experience.. if anyone wants 
me to look at anything, feel free to drop me a line (for an example, see the 
recently released reverse engineered opensource nforce ethernet driver, 
forcedeth).

No, it has always been fairly empty, and nobody has been working on it
recently. It's all yours...

Please don't write any code for Wine that would be based on
disassembling Windows code.

However, most of it is implemented already in winedbg. It has been a
long-term plan to gradually move code from winedbg to imagehlp (or the new
and similar debugging DLL, dbghelp). PDB files are also supported in winedbg
(so no investigation of the format should be needed). However, I'm not sure
whether .dbg files are supported. They could be quite useful when a crash
occurs in a native DLL (that doesn't have an associated PDB file) and Wine
is the cause.

It would be nice if we could move this code to imagehlp and debughlp so
ReactOS can make use of the work.

Thanks

They are... but it also depends on the MS debugging format used. Ulrich 
Weigand wrote some support for some formats (NB09, NB10 and N11), but 
latest formats are not supported.

I started some time ago porting the winedbg stuff inside dbghelp (I have 
a skeletton from this later DLL). If someone is interested to spend some 
time on this, I can provide what I have.
