This is the code in C that implements the function
"lib.icalcomponent_free()".  There are similar pieces of code for all
other functions.  What are you asking specifically?  If it's ok to
call such functions from a __del__()?  Yes, it is.

Sometimes you can use ffi.gc() instead and give the function
"lib.icalcomponent_free" directly as a second argument; then you don't
need a __del__.  But if the __del__ solution suits your case, then
that's fine.


A bientôt,

Armin.
