Smobs are GUILEs mechanism of exporting C(++) objects to the Scheme
SCM smobbed_copy ().
Simple smobs are created by adding the
- DECLARE_SIMPLE_SMOBS(Classname, ) to the declaration
+ DECLARE_SIMPLE_SMOBS(Classname) to the declaration
2. Complex smobs are objects that have an identity. These objects
carry this identity in the form of a self_scm () method, which is a
list = scm_cons (p->self_scm (), list);
scm_gc_unprotect_object (p->self_scm ());
- Complex smobs are made with DECLARE_SMOBS (Classname, ) in the class
