BSON_WRITER_GET_LENGTH(3)

💖 BSON_WRITER_GET_LENGTH(3) 💖

okay so bestie, this one's from libbson and it's literally the cutest little getter function 🎀

---

✨ SYNOPSIS ✨

size_t
bson_writer_get_length (bson_writer_t *writer);

🌸 PARAMETERS 🌸

• writer — a bson_writer_t. that's it. that's the whole parameter list. slay 💅

🦋 DESCRIPTION 🦋

so what it does is it fetches the current length of the content that's been written by the buffer — and yes, that includes the initial offset, no cap. it also counts a partly written document that's currently being written, so even if you're mid-document it's still giving you the real number. 🔥

it's honestly so useful when you wanna vibe check whether you've passed a given memory boundary that can't be sent in a packet 👀. and if you do need to bail on the document you're currently writing, go see bson_writer_rollback() to abort it — iykyk.

ngl this is the kind of function that just sits there quietly being correct and we love her for it 💜

⭐ RETURNS ⭐

the length of the underlying buffer. that's the tea 🍓
