BSON_STRERROR_R(3)

💅 BSON_STRERROR_R(3) — your girl's guide to libbson's error-string era

okay bestie, sit down, hydrate, and let me tell you about bson_strerror_r — she lives in the libbson universe and honestly? she's a tiny legend. 🎀

---

✨ SYNOPSIS ✨

char *
bson_strerror_r (int err_code, char *buf, size_t buflen);

that's the whole thing. short, sweet, iconic. 👑

---

🌸 PARAMETERS 🌸

• err_code — an errno. yep, that kind of errno. the number your code is currently crying about. 😭
• buf — a location to store the string. like, a lil parking spot for the error text. 🅿️
• buflen — the size of buf. keep it honest, bestie, we're gonna trust that number. 🙈

---

🦋 DESCRIPTION 🦋

so here's the vibe: this is a portability wrapper around strerror(). that's it. that's her whole job. she takes the messy, platform-dependent reality of "how do I turn an errno into a human string" and hands you one consistent function so you don't have to do the #ifdef dance yourself. it's giving main character energy for something so small. ✨

no cap, it's literally just glue code, but it's our glue code. 🫶

---

💖 RETURNS 💖

she returns either the buf parameter you passed in, or an internal string. so like — don't assume it's always your buffer, okay? check the return value, that's the whole point of a return value. 💅
