wine users - Aug 2006 - newbie tries to call windows dll function

Dear list,

I (running fedora core 5 linux) have a native Windows (actually do not
know which windows version) dll file, in which are functions I want to
call in my Linux program. That is why I installed wine, to see whether I
could make this work :)

I know exactly what functions are in the dll, what their prototypes are,
but I do not have the source, only the myfile.dll.

Now, what I don't understand is that they are not listed below. Only those
four Dll... functions.
I could convert myfile.dll to myfile.dll.so using winemaker;make, great :)
But it only seems to have those four functions as well.

I guess this means the functions are not exported, but the dll file does
work running in windows (does this mean it's not necessary to have such an
export table?)

Does anybody know what more I have to do?
I'm using
http://www.isotton.com/howtos/C++-dlopen-mini-HOWTO/C++-dlopen-mini-HOWTO.html
to try to call the functions I want in myfile.dll.so, but they cannot be
loaded.

By the way, 'strings myfile.dll' does reveal all those function names I
want to call.

Thanks for any help,
JeeBee.

You need to give a little more background.
What does the DLL do?  What program are you trying to call it from?

The easiest thing would be to write a Windows app that
uses the DLL.
The next easiest thing would be to write a Winelib app that
uses the DLL.
You can't write a plain old Linux app that uses the DLL,
at least not easily.  (This is something we'd like to support
but haven't gotten around to.  And even after we support it,
it's going to be a bit odd.)
