You're right, it needs an fflush() after each write, and I also forgot 
an fclose() at the end. I typed that thing up in my e-mail buffer, so 
there were admittadly some bugs. =)

Anyway, my point was that it's pretty easy to make a program that does 
almost exactly what every other "wipe" or "shred" program does for 
Windows if you want one. (BTW, if anyone wants the code I posted before 
with lots of little tweaks and fixes I added for fun after I sent the 
original message, I'd be happen to send it to ya).

All the arguments about possible not overwriting in place don't apply 
if you have a FAT filesystem. Once the data is out of the write cache, 
It does always overwrite files in place, assuming you don't resize the 
file first. (=

Obviously, no shredding or wiping program is going to be absolutely 
foolproof, but that doesn't mean that you shouldn't use one at all.
