New subject: Windows API database

28 Jan 2003

      So for starters, we want something like this?  It doesn't look very
impressive.  :)
http://home.ptd.net/~compsol/imported_dll.txt
However, my system is by no means a clean install of WinXP home so most of
thos DLLs probably don't belong to windows.

Oh, ok.  Cross-referencing DLL imports and exports.
Yeah, that sounds like a job for a simple perl script.
All you need to output is DLL name and what DLLs it imports from.
Just generate a flat text file for starters, then
later postprocess that into an ascii tree or graph.
It's going to be a messy little graph, I bet.

I would be interested in knowing more about the goals of this project.

Don't consider me officially working on such a thing just yet.  I have
...
...

no real perl experience, but would like to learn.  First I'd like to
...
...

know more about what I'm up against.
...

I'm not sure what project you're talking about, but I can make a few
...
...
wild guesses...
...
...
...
...
...
...
...

Is there a specific set of dll's and exe's we want included in the

...
...
...
database or does it need to scan and gather a list of all dll and exe
...
...
...
files?  That would suggest a clean OS install is necessary.
...
...
...
...
Sure, a clean OS install is probably good.  Many of the
...
...
APIs exposed by even the clean OS install may not be
...
...
needed if no application calls them, but it's hard to know
...
...
that in advance.
...
...
...
...
We might want to also scan applications to see what APIs
...
...
they actually use, but that's real hard.
...
...
...
...
...
...
...

What information should be in the database? (OS ver, name of dll or

...
...
...
exe, name of imported dll, APIs and whether they are imported or
...
...
...
exported, etc.)
...
...
...
...
Maybe use the same format as we use in the souce tree?  e.g.
...
...
scanning advapi32.dll should produce something that looks very
...
...
much like
...
...
http://cvs.winehq.com/cvsweb/wine/dlls/advapi32/advapi32.spec?rev=1.32
...
...
...
...

Will a single MySQL table do or does it need to be a relational

...
...
...
database with multiple tables?
...
...
...
...
IMHO no SQL is needed.  The database should be plain text
...
...
files checked into CVS.
...
...
...
...
...
...
...

Anything else you can tell me about this task?

...
...
...
...
Compare with other standards which provide lists of API's, for example:
...
...
http://www.linuxbase.org/spec/
...
...
http://www.unix.org/
...
...
http://www.ecma.ch/ecma1/STAND/ECMA-234.HTM
...
...
to get some ideas.  Of course, these are formatted all fancily,
...
...
and cover different operating systems, but the goal is similar:
...
...
to provide an authoritative list of APIs.
...
...
Ideally, the result could be part of a submission to a
...
...
standards body.
