Device drivers in Wine

[Damjan Jovanovic]

Hi

Basically, I have a Windows user-space device driver,
and I need to get it working under Linux.

I note Wine has some "device" functions
(FILE_CreateDevice(), and DOSFS_OpenDevice()). How do
these work and what do they do? Are they documented
anywhere?

And is there a way to open and use a Windows DLL from
a Linux program?

Thanks
Damjan

what driver is it ? if it is run as a standard DLL, just open the driver 
as a DLL, and call it's entry point.

the simpliest way is to make your program a winelib. Otherwise, look at 
what the mono or the Ardour folks did lately (search on wine-devel archives)

It's a scanner driver, consisting of a TWAIN plugin,
plus about 20 DLL's and a kernel-mode driver. But I
know exactly what the kernel-mode driver part does, so
it should be easy - provided I can change what
CreateFileA(), CloseHandle(), DeviceIoControl(),
ReadFile() and WriteFile() do.

You mean link it with winelib when compiling, or build
a .so library you link in at runtime?

By the way, how essential is STI.DLL for getting a
scanner driver to work, and can you use the one
provided with Windows?

Thanks

I mean creating what wine calls a winelib app: it uses wine magic for 
startup (it ends up being a .so file run by the wine loader, and not a 
full native ELF application).

Dunno. As any DLL (especially the ones without hardware relationship) 
should be run in Wine, but YMMV (depending on the dependencies of the 
said DLL).
