File media type

[Ove Kaaven]

I'm trying to think of a way to make multi-CD installers work under Wine.
Right now, the hardest part is that when the installers tell you to change
discs, the Setup.exe file mappings are still open. I'm thinking of making
Wine not map the file, but read it straight into RAM, if the executable
to be mapped is on removable media.

But since to do this, MapViewOfFile needs to know the media type, and the
file name is only known in CreateFile, I apparently need to store the
media type in the wineserver object to accomplish this.

Would changing the wineserver protocol in this way be a good idea?

That's a very interesting issue.  It's cool that
Wine is to the point where such things matter.

[ Off topic - I've been thinking on and off
about that other project that added native PE support to
BSD.  I wonder how / if they handle this issue.

Perhaps this is something that Linux itself would want, even
for native executables.  I suppose it might be a mount option.
Hmm hmm.  ]
