From 303680ebcd5adaac2934b63a0edc2d9d1a36d7fb Mon Sep 17 00:00:00 2001 From: David Oberhollenzer Date: Wed, 12 Feb 2020 02:22:31 +0100 Subject: Implement a more explicit object system Make every dynamically allocated, opaque data structure inherit from a common sqfs_object_t structure with common entry points (e.g. destroy). This removes tons of public API functions and replaces them with a simple sqfs_destroy instead. If semantics of the (until now implicit) object system need to be extended, it can be much more conveniantely done this way.
