I personally like the OUT better since it is official defined by Microsoft. > BTW, how many are IO? I would suspect most are O only... For strings, not that many. Can't think of any right now. However there are quite a few LPDWORD that specifies the allocated length of the output buffer and the function is should write the used length (or needed length, if the function faild) in the pointed to DWORD. Other than that it is quite uncommon IIRC.

For the record I see absolutely nothing wrong GNU C handles __declspec(dll{import,export}) and just put useful information in some aproprietely named section. After all you can always strip the section if don't want it and BTW if why don't want it why use __declspec(dll{import,export}) at all...

I can write code if you, Dimitrie or whomever specify the output format... > Of course having an imperfect parser also means we cannot use it for > the export info, because unlike relay debugging it needs to be 100% > correct.

This isn't happend soon either. It might not be THAT difficult, however the code need not just work it needs be well structured and organized as well if any reasonable guarantees of correctness can be made.

I see no reason to get rid of it. If people doesn't have Perl installed just don't run them. But then most people probabably have Perl installed anyway...

No big deal, really... You mean just add a OUT before the type. That is quite easy to parse.

It is not really dependent on Perl. Of course you can't run regression test written in Perl without Perl... > How is all of this going to effect building on > Windows/ReactOS with Mingw?

I understand. On the other hand we can't hold back "progress" just because of difficulties of installing certains tools on certain platforms. But judging from Alexandres message it won't be happing anytime soon... > Note: even using perl on cygwin is still borked atm for the > regression suite and I havent even > tried winapi_check. another option may be to look at active > perl for windows but I really dont > like that idea. ActivePython for Windows works nicely. Haven't tested ActivePerl...

Sure, but I have written the Perl code I know how ad hoc it is. It works under reasonable assumptions however beyond that... But I'm not really against it, I'm just pointing out potential problems...

Standard controls
by Dimitrie O. Paun 11 Sep '02

11 Sep '02

And since I feel frisky lately, I want to run another idea by you guys. We have the standard controls bundled with USER, just like Windows. In fact, it seems XP bundles them with the common control, but that's another story. My point is, that there's no logical reason they should be in USER. In fact, in the future we may want to provide other implementations which integrate better with GNOME and/or KDE. So what about moving them to a separate DLL, say winectrl? -- Dimi.

winebuild & (name, heap, init)
by Dimitrie O. Paun 11 Sep '02

11 Sep '02

Alexandre, Why don't we take the following directives: name, heap, init out of the .spec file, and put them in the Makefile (transfered to winebuild through command line args)? Some of them are supported in .DEF file as well, but all of them are supported as arguments to LINK. I think it will gain us flexibility if we also support them as command line arguments. With that in mind, it would be neat if we could specify a flag at configure time to build most of Wine as PE with a cross mingw. It would be way cool if I could take the same comctl32.dll I have on Linux, copy it on my Windows machine, and test it out... Anyway, what about a patch to at least support all of this as command line options as well? -- Dimi.
