As proposed here: https://www.redhat.com/archives/libguestfs/2019-August/msg00130.html I didn't actually read Eric's replies to that yet because I've been concentrating on writing these patches all day. Anyway here they are and I'll look at what Eric said about the proposal next. Rich.

...hree-tuple in C: main callback, free callback, and user data - is sufficient to give language bindings the flexibility they need to pack up a C struct containing everything needing cleanup at the end of the lifetime, whether or not there is also a language callback in play) > >>> + new_callbacks = realloc (h->free_callbacks, >>> + sizeof (struct free_callback) * new_alloc); >> >> Should we start relying on reallocarray() to guarantee no multiplication >> overflow?
