MONGOC_APM_CO...CTION_ID_INT64(3)

✨ MONGOC_APM_CO...CTION_ID_INT64 ✨

ok so this one is a libmongoc page, bestie — yes, the libmongoc, the C driver for MongoDB, we love her 💅 — and it's all about a tiny little getter function that hands you a server connection ID as an int64_t. short page, iconic energy, let's go 🎀

---

✨ SYNOPSIS ✨

int64_t
mongoc_apm_command_started_get_server_connection_id_int64 (
  const mongoc_apm_command_started_t *event);

🌸 DESCRIPTION 🌸

so this returns the server connection ID for the command 🫶 like, the ID of the connection, not the ID of the server — those are two whole different things, do not confuse them, i'm literally begging 🙈

the server connection ID is distinct from the server ID (which, fyi, is what mongoc_apm_command_started_get_server_id() gives you, different function, different vibe). and where does this connection ID come from? it's returned by the hello or legacy hello response as "connectionId" from the server on 4.2+ ✨ so if you're on an older server, she might not be there, iykyk 💀

🦋 PARAMETERS 🦋

• event — a mongoc_apm_command_started_t. that's it, that's the whole parameter, main character behavior honestly 👑

⭐ RETURNS ⭐

the server connection ID as a positive integer 🥳 or -1 if it is not available 😭 (yes, negative one means "no connection ID for you", don't @ me, that's just how it is)
