I think I finally made it work, close to what I wanted. This could be good for future reference for anyone trying to do something similar. The code is at https://gist.github.com/anonymous/8897943.
I have two questions about it: 1) calling jl_gc_disable() and jl_gc_enable() is ok in that context? (see link above) 2) I still don't know how to avoid passing a pointer to the module I want to get the type from to the C call. Thanks.
