I wrote a big Gnu C++ program (an emacs-type text editor). I found today that
various DOS interrupts that are supposed to make specific fault returns when I
try to access a nonexistent drive, when Novell Netware is active act very odd
and cause aborts in my program; and I have to run with Novell active most of
the time. Luckily I have managed to cobble matters together so that a
nonexistent drive looks to a user of my program like an empty drive that can't
be written to. But this is unsatisfactory. Please how in Gnu C++ can I find
easily at run time for(i='A';i<='Z';i++) whether drive i exists? And I don't
want in the process any empty floppy or CD-ROM drives making rude noises at me
or wanting Abort/Fail/Retry. I don't mind if an empty floppy drive is treated
as nonexistent. It seems easy enough: the File Manager in Windows gets it
right every time and displays across the top of its window a row of little
disk drive icons, one for each existing logical drive.
