DOSFS_GetFullPathName

[Enrico Horn]

Hi,
Ive been trying to get Heroes III to work with wine
and I found that it cant load some file it needs
because DOSFS_GetFullPathName
return the path to that file without the backslash at the end
although heroes3 asked for it with a backslash at the end.
it asks for .\\DATA\\ and the method returns
<path to heroes3>\DATA  <---- missing backslash
in the method the last backlash is removed when
no driveletter is in the requested pathname.

I'd like to know why this was implemented like this as I
cannot understand the reason for it.

Thanks for your help

I know that there's some trailing \\ problem somewhere,
and I intended to fix some functions but haven't had enough time yet.

What you want is finding out which Win32 API function returns this
string to your program.
Then either fix it directly in this function, or, if really appropriate,
fix it in some Wine internal function, and maybe that is actually
DOSFS_GetFullPathName like you said.

This is Debian bug #101751 (which includes a somewhat ugly patch, it was
submitted to wine-patches, but so far ignored by the wine community).
