Cyc_scm_call Cyc_scm_call_no_gc

Cyc_scm_call() object Cyc_scm_call ( gc_thread_data *  parent_thd, object  fnc, int  argc, object *  args  ) Setup a full call into Scheme code. This is somewhat expensive as we setup a new thread object and register it with our GC. On the other hand the called code can do anything "normal" Scheme code does, and any returned objects will be on the heap and available for use by the caller.
