MONGOC_BULK_OPERATION_UPDATE(3)

✨ MONGOC_BULK_OPERATION_UPDATE 💅

okay bestie, gather round, because this one lives in libmongoc and it's like... a little vintage, but we still need to know her 🎀

---

🌸 SYNOPSIS 🌸

void
mongoc_bulk_operation_update (mongoc_bulk_operation_t *bulk,
                              const bson_t *selector,
                              const bson_t *document,
                              bool upsert);

---

🦋 DESCRIPTION 🦋

so what does she do?? literally just queues an update as part of a bulk operation. that's it. that's the whole vibe. she does NOT execute anything — she's the planner, not the performer 💅 the actual main-character moment happens when you call mongoc_bulk_operation_execute() to run the entire bulk operation. periodt.

🚨 important, no cap: document MUST only contain fields whose key starts with $. like, that's the rule. see the update document specification for more details if you need the full lore iykyk.

and ngl, this function is superseded — she's been gently replaced by mongoc_bulk_operation_update_one_with_opts() and mongoc_bulk_operation_update_many_with_opts(). she's still iconic, but the new girls are running the show 🫶

🎀 PARAMETERS 🎀

• bulk — a mongoc_bulk_operation_t. your whole bulk-operation situation, the container of the queue ✨
• selector — a bson_t that selects which documents to remove 👀 (yes, that's what the docs say, bestie, i don't make the rules)
• document — a bson_t containing the update document, aka the actual change you're bringing 🌈
• upsert — true if an upsert should be performed. flip that flag if you want upsert energy 💖

---

💀 ERRORS 💀

errors don't get thrown from here at all — they're propagated via mongoc_bulk_operation_execute() 😭 so if something goes sideways, that's where you go looking. not here. not today.
