✨ BSON_SNPRINTF(3) ✨

okay bestie, so this is a page from the libbson manual and honestly? it's a little cutie. let's get into it 💅

🌸 SYNOPSIS 🌸

int
bson_snprintf (char *str, size_t size, const char *format, ...);

like, look at that signature. it's giving variadic icon. 🎀

🦋 PARAMETERS 🦋

  • str — the destination buffer. this is where the magic lands, the main character's stage. 🎤
  • size — the size of str. yes babes, you have to tell it how big your buffer is. no cap. 📏
  • format — a printf style format string. the classic. the blueprint. the vibe. ✨

💖 DESCRIPTION 💖

so what does it actually do? it's a portable wrapper around snprintf(). that's it, that's the tweet. 🐦

but wait — there's more, because it also enforces a trailing \0 in the resulting string. so your string is always properly terminated. no dangling, no chaos, no undefined behaviour meltdown. she said "i will NOT be leaving you unterminated." periodt. 💀✨

🔥 RETURNS 🔥

the number of bytes written to str. that's your receipt, bestie. 🧾
