Hi,
I am implementing a plugin that allocates several resources. I need to
cleanup some of these resources when QEMU finishes executing the guest
application. Where is the best exit point to place my cleanup functions?
I have tried registering a function call "atexit" but it does not seem
to work. Any suggestions? At the moment, I am looking for a solution for
x86_64 (user emulation mode).
Kind regards,
Rafael

For linux-user have a look at preexit_cleanup() in linux-user/exit.c
