You can trace what it does by looking at the code for exit, found in
src/toplev.cc.  Here is a summary:

If any functions have been registered by calls to atexit, Octave runs
them and then flushes the octave_stdout stream.

Then it

  * restores the terminal state

  * cleans up and saves the history

  * closes any open plot streams

  * closes any open octave_stream files

  * cleans up any tmp files

  * flushes the octave_stdout stream

  * exits
