I had a weird situation with my application where the user deleted all
the database files while the app was still reading and writing to the
opened file descriptor. What was weird to me was that the app didn't
complain. It just went merrily about it's business as if nothing were
wrong. Of course, after the app shut down all it's data was lost.
Since I didn't expect this behavior I wrote a simple little program to
test it. Sure enough, you can rm a file that has opened file
descriptors and no errors are generated. Interestingly, sun solaris
does the same thing. Since this is the case, I thought this might be
a feature instead of a bug (ms-win doesn't allow the rm). So, my
question is where is this behavior defined? Is it a kernel issue?
Does POSIX define this behavior? Is it a libc issue?
I tried to google this, but couldn't think of the right terms to
describe it. As I'm not on lkm, I would appreciate a CC: to
