EC_HTABLE_HAS_KEY(3)

✨ EC_HTABLE_HAS_KEY ✨

okay bestie, welcome to the ec_htable_has_key page from the Libecoli Programmer's Manual 💖 this one is short and sweet and honestly? iconic. it does exactly one (1) thing and it does it flawlessly.

---

🌸 NAME 🌸

ec_htable_has_key — bestie, this is the lil check that asks: does this hash table contain this key or not?? 👑

---

🎀 SYNOPSIS 🎀

#include <ecoli/htable.h>

bool ec_htable_has_key(
    const struct ec_htable   *htable,   /* The hash table. */
    const void               *key,      /* The key. */
    size_t                    key_len   /* The key length. */
);

so the way this works is you hand it three things and it just tells you yes or no. no drama, no side quests, no notes. 🦋

• the htable — that's your hash table, the main character. you pass it as const struct ec_htable *.
• the key — that's the key you're looking for, a const void *, so it can literally be anything, we don't judge 💅
• the key_len — the length of that key, as a size_t, because the table can't read your mind and it needs to know how many bytes we're talking about fr fr

---

🌈 RETURN VALUE 🌈

it returns true if it contains the key, else false. that's it. that's the whole vibe check. 💀✨

not me checking a key and getting a plain old bool back — no error codes, no surprises, just truth. we love a low-stakes icon.
