A common bug in these files involves pointer aliasing. handle-with-cache.c

Before we discuss caching, we must define the handle. In idiomatic C, a handle is an opaque pointer. The user of an API receives a void* or a pointer to an incomplete struct, ensuring they cannot modify internal state directly. pthread_rwlock_t cache_lock; return status; A common bug in

// The cache itself (often a global or passed context) static GHashTable *handle_cache = NULL; static pthread_mutex_t cache_lock = PTHREAD_MUTEX_INITIALIZER; handle-with-cache.c

: A function like ssize_t handle_with_cache(...) that acts as the entry point for the application.

: Algorithms like LRU (Least Recently Used) or TTL (Time to Live) that decide which items to keep and which to evict when the cache is full. Implementation Essentials
