42 * Naming: BKE_id_ vs BKE_libblock_
44 * WARNING: description below is ideal goal, current status of naming does not yet
45 * fully follow it (this is WIP).
47 * BKE_id_ should be used for rather high-level operations, that involve Main database and
48 * relations with other IDs, and can be considered as 'safe' (as in, in themselves, they leave
49 * affected IDs/Main in a consistent status).
51 * BKE_libblock_ should be used for lower level operations, that perform some parts of BKE_id_ ones,
52 * but will generally not ensure caller that affected data is in a consistent state
53 * by their own execution alone.
55 * Consequently, external code should not typically use BKE_libblock_ functions,
56 * except in some specific cases requiring advanced (and potentially dangerous) handling.
