[Chicken-users] [newbie] destroying foreign objects

[Marco Maggi]

Ciao,

  I   am  skimming   through   Chicken's  documentation   to
understand what it  can do; is there a  way to automatically
apply a  finalisation function when  a pointer to  a foreign
object   (C  language   structure)  is   garbage  collected?
Something like guardians.

TIA
