Hello,
I want to embed the racket interpreter to create a C interface for a
certain r6rs scheme library. It comprises diverse functions which return
complex scheme objects. These, in turn, may be passed to other functions
within the library (and therefore shouldn't be gc'ed along the way).
I got it so far that I call scheme_main_setup, passing along my run
function which loads the library into the scheme environment and does
the actual scheme calls. This approach, however, isn't suitable for what
I want. When run returns, all is gone and gets garbage collected (I think).
I'd rather have a typical interface with an initialization function
(that loads the environment and returns normally), some wrapper
functions (which call scheme_dynamic_require and scheme_apply), and a
destructor function.
Probably I'd have to use scheme_set_stack_base rather than
scheme_main_setup. Obviously I would want to reuse the environment
throughout all calls. There hopefully is a way to prevent the garbage
collector from collecting it, and also the other scheme objects which my
library returns.
My question is: is this feasible? How would I go about it? Thanks for
your help!
Regards,
Daniel
