💅 MONGOC_ERROR_HAS_LABEL 💅

okay so bestie, welcome to libmongoc's very own label detector 😌 — this little function (mongoc_error_has_label, if we're being formal) is your new fave when an operation flops and you need to know why. It's giving "detective but make it C" 🔍✨

✨ SYNOPSIS ✨

bool
mongoc_error_has_label (const bson_t *reply, const char *label);

So here's the vibe: you hit a failed operation, you've got a reply, and you want to know if it's carrying one specific error label. That's literally the whole job 🫶. It tests whether a reply from a failed operation includes a specific error label — see Error Labels for details (iykyk), and see mongoc_client_session_start_transaction() for example code that demonstrates their use 👑.

🎀 PARAMETERS 🎀

  • reply — A non-NULL pointer to overwritable storage for a bson_t to contain the results 💖. Note the non-NULL part, bestie — don't be out here passing NULL, that's not the move 🙈.
  • label — The label to test for, such as "TransientTransactionError" or "UnknownTransactionCommitResult" 🦋. Drop the exact string you're hunting for in here.

⭐ RETURNS ⭐

Returns true if reply contains the error label 💀🔥. That's it, that's the whole return situation. No cap.
