Is there a mechanism in Ethereal to call a user-specified function just

I guess you could use "atexit()", at least on those platforms that
support ANSI C. ("ANSI C" here doesn't mean "function prototypes", it
means "all of ANSI X3.159-1989, or the ISO equivalent, or the later C99
standard. complete with library routines".)
However:
In some module i am coding, i'm allocating free store, which has to be
persistent during the whole ethereal session and which i would like to
free
on exit.
on, as far as I know, *all* of the platforms on which Ethereal runs,
the entire address space of a process is freed when the process exits,
so it's not as if memory takes up swap space forever if it's not freed
by the application on exit.
Note also that "the whole Ethereal session" could involve more than one
capture file, so if it truly has to be persistent during the entire
session, that presumably means it'd be used even if you close one
capture file and read in a new, completely-unrelated, capture file.
