Subject: C ext to Ruby interaction between a Module and a Class


I'm presently writing C extension to Ruby (under and for Mac OS X).

i do have a Ruby Module called "ROSXUtils" and i want to return a
class coming from another C ext to Ruby. The class being RAliasFile.

i don't know exactly how to do that.

for the time being i've put the class RAliasFile under a sub-directory
"lib" of my ext/ (of the Module ROSXUtils)  :

ext/
    extconf.rb
    lib/
        extconf.rb
        dll_p.c
        dll_p.h
        raliasfile.bundle
        raliasfile.c
    rosxutils.bundle
    rosxutils.c
    UnixUtils.c
    UnixUtils.h


BUT, for the time being in order to use, from C, the RAliasFile class,
i'm obliged to use :

rb_eval_string("require '/absolute/path/to/raliasfile'");

then to return an instance of this class :

VALUE alias = rb_eval_string("RAliasFile.new(arg)");

this works but isn't elegant ???


what could be the best way to instantiate a class being a C ext to
Ruby from a module being also a C ext to Ruby ???


also is my dir hierarchy shown above the best way ?

i'd like better having the class RAliasFile included in the
rmosxutils.bundle...


any comment appreciated ;-)
