Sorry if this is the wrong list. I've search google, but have not
found solution to my problem.
I have a long running application which split out lots of debugging
information. I can't redirect the output to a regular file because
that file would grow and eat up all the diskspace. I can't redirect
to /dev/null. What I want is the last 1MB of the output before my
application terminated. So I need to create a special file / device
on the system. Please tell me if there is an existing device that I
can use, or point me in the right direction so that I can role my own
device.

AFAIK this will output the file after the app termination. He wants to know the
log before that.
Just write your own reader which will output last meg in some intervals...
