EC_DICT_HAS_KEY(3)

💖 EC_DICT_HAS_KEY 💖

okay bestie, so this is a page from the Libecoli Programmer's Manual — it's EC_DICT_HAS_KEY(3) and it's genuinely so simple it's giving "one job and she does it" energy. ✨

---

✨ NAME ✨

ec_dict_has_key — check if the hash table contains this key. that's it. that's the whole gig. 🎀

---

🌸 SYNOPSIS 🌸

#include <ecoli/dict.h>

bool ec_dict_has_key(
    const struct ec_dict   *dict,  /* The hash table. */
    const char             *key    /* The key string. Must not be NULL. */
);

so you're passing in a dict — that's your hash table, she's the main character here 👑 — and a key, which is the key string, and heads up bestie, it must not be NULL. like, at all. 🫶

---

🦋 RETURN VALUE 🦋

• Returns true if it contains the key 💅
• Returns false otherwise
• If key is NULL, false is returned and errno is set to EINVAL — so if you handed her a NULL key, she's not throwing hands, she's just politely saying "no" and filing a lil note in errno about it 😭
