gobject clarification regards to instance memory initialisation

[Stefan Kost <kost imn htwk-leipzig de>]

hi hi,

I am currently updating the gobject tutorial from mathieu lacage again.
One question for the gurus' (I was scanning the code, but are not sure about
this). Frim the viewpoint of a class writer, do I have to initialise fields in
my object instance that should be 0/NULL or is the memory cleared?
In other words in my class_init/instance_init methods can I expect that
instance->XX
object->>XX
fields are 0 (except the parent fields of course)?

Stefan
