Subject: [ruby-talk:17798] GC mark

"The mark routine will be called by the garbage collector during its
``mark'' phase...", "...mark function needs to identify these objects
using rb_gc_mark(value)." 

But "my structure" is not my and it does not "know" anything about Ruby.
The structure references other C-structures wrapped by Ruby objects. How
can I determine the value of the referenced C-structures while I have
only a pointer to the containing C-structure? I need at least VALUE of
the latter.
