You might store this value (a long) into +a class static variable, or a file static variable.

Lets set the cdr to +NULL, and then check for that in all of the primitive functions that +use your smob. We'll call this notion 'live'; a scheme object is +'live' if the C++ representation still exists, it's dead if the C++ +object is gone. You can still have references to dead objects in +scheme code; it's just an error to use them. This idea is stolen from +Emacs's handling of buffers ('buffer-live-p' and friends). + +Add another function, foo_live_p: + +static int +foo_live_p(SCM obj) +{ + return(foo_p(obj) && SCM_CDR(obj) != NULL); +} + +In you destructor, you need to do: + +~Foo_class() +{ + SCM_CDR(this->obj, NULL); +} + +When writing new primitives, now just check foo_live_p(). + +I hope the above helps, + +-russ + + +-- +"Even if you are on the right track, you'll get run over +if you just sit there." + --Will Rogers (1879-1935) + +***************************
