BSON_STRING_APPEND_PRINTF(3)

💅 BSON_STRING_APPEND_PRINTF 💅

okay bestie, welcome to the libbson section 3 glow-up ✨ this one's all about bson_string_append_printf, and no cap, it's deprecated so listen up 🫶

⚠️ WARNING: Deprecated since version 1.29.0. 😭 she's retired, she's a legacy icon, she's not the one you should be calling anymore.

---

✨ SYNOPSIS ✨

void
bson_string_append_printf (bson_string_t *string, const char *format, ...);

returns literally nothing (void, she gives you vibes and side effects only 💅) and takes a bson_string_t * plus a format string plus ... because she's a variadic queen 👑

---

🎀 PARAMETERS 🎀

• string — a bson_string_t. that's the string you're appending to, bestie, the main character 🎀
• format — a printf style format string. the recipe, the blueprint, the whole aesthetic 🌸

---

🌸 DESCRIPTION 🌸

so like bson_string_append() but with a glow-up: she formats a printf style string first, and then appends that to string. format-then-append, that's the whole bit ✨

🚨 WARNING: the length of the resulting string (including the NULL terminator) MUST NOT exceed UINT32_MAX. like, that is not a suggestion, that is not a soft launch, that's a hard limit. do not test her. 💀
