Wireshark · Ethereal-dev: [Ethereal-dev] Freeing memory on exit?

["Lars Ruoff" <lars.ruoff@xxxxxxxxxxxxxxxxxx>]

Is there a mechanism in Ethereal to call a user-specified function just
before Ethereal exits?
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.
In C++, i would make this with a global static object, freeing the memory in
the destructor, but i don't know how to do something similar in C.
A solution would be to register a callback-routine which would be called by
Ethereal on exit.
I there perhaps something like that implemented?

Lars.
