< p > The cache enforces an upper bound (max_items) on the number of tracked entries. Insert helpers are expected to evict (or refuse) when the limit is exceeded (strategy defined in implementation; current behavior may be simple non-evicting if not yet implemented as a true LRU). The cache pointer holds the uthash root (NULL when empty).< / p >
