Hello Andrei, it would only help if the schema used is always the same so that it is trustably unique. The following two lines achieve that:
char *key; spprintf(&key, 0, "%s::%d", Z_OBJCE_P(obj)->name, obj->value.obj.handle); Yep would help in a few edge cases and allow O(1) implementation of ObjectStorage. regards marcus Thursday, August 11, 2005, 1:30:14 AM, you wrote: > What we really need is a get_hash_t handler on the object, so that each > object knows how to hash itself.
