Freeing allocated C-memory by GC (destructors)

[Oliver Bandel <oliver@first.in-berlin.de>]

Hello,

after using some non-permanent allocating C-stuff
together with OCaml, I think about going one step further and
now have allocated memory from C represented as OCaml-variables
(in the concrete example I have married some of my C-stuff that
uses jpeglib to get information from picture-files, and
now think about representing complete picture-data as
OCaml-variables).

So, I want to have the possibility to have malloced/calloced
data avaliable in OCaml, and that the GC calls C-destructor-
functions (using free(3)) when the values are of no use anymore.


How to say the GC, which is the destructor-functions
for a variable, which has been created?

TIA,
   Oliver
