Opening raw character device in DOS/Windows 98

[rxhofman]

Hello all,

I want to create my own filesystem on a flash memory card. How can I
open the card as a raw character device?

On a unix-like system I can just open /dev/hdx as a file and do
whatever I want. How can I achieve the same thing under MS DOS or
Windows 98?

Thanks!

filesystems and flash memory cards and raw character devices
are all system-specific, not mentioned by the standard C language.

whatever I want. How can I achieve the same thing under MS DOS or
Windows 98?

You'd need to ask in a system specific newsgroup. All that
C provides is fopen() with a "b" modifier on the file mode
(to indicate binary). Determining the correct filename to open
(or whatever else needs to be done to get a hook to the device)
is system specific.

Let me just say, with all sincerity and love:

Off topic. Not portable. Cant discuss it here. Blah, blah, blah.

Thanks, Walter. Apologies for the off-topic post - I wondered if there
was some strange and wonderful system call provided on DOS platforms
that C experts would be familiar with. All the DOS newsgroups seem to
have very little activity.
