BSON_ITER_FIND_W_LEN(3)

💅 BSON_ITER_FIND_W_LEN 💅

okay so bestie, this one lives in the libbson manual and it's literally the "find my key but make it length-aware" function 🎀 she's giving precision, she's giving control, she's giving iykyk.

---

✨ SYNOPSIS ✨

bool
bson_iter_find_w_len (bson_iter_t *iter, const char *key, int keylen);

---

🌸 PARAMETERS 🌸

• iter — a bson_iter_t. that's your iterator bestie, the little scroller doing the actual walking 🚶‍♀️
• key — a string containing the requested key. the thing you're hunting for 🔍
• keylen — an integer indicating the length of the key string. you're telling her exactly how long the key is, no guessing, no cap 💅

---

🦋 DESCRIPTION 🦋

so the bson_iter_find_w_len() function shall advance iter to the first element named key — or, if it can't find it, exhaust all the elements of iter. one of those two things, periodt ✨

if iter gets exhausted, false is returned and iter should be considered invalid. like, don't touch it, she's done, she's clocked out 😭💀

key is case-sensitive, highkey important. if you want the case-folded version instead, go see bson_iter_find_case() — she's the chill twin 🫶

---

⭐ RETURNS ⭐

true is returned if the requested key was found 👑 slay.

if not — iter was exhausted and should now be considered invalid. yeah. that's the whole vibe check and it failed 🙈
