💅 MONGOC_CLIENT...ANSACTION_CB_T(3) 💅

okay bestie, so this little icon is one of the callback typedefs from libmongoc — yes, that libmongoc, the MongoDB C driver, we're in the C lane now and it's giving big-brain energy 🧠✨. Sit down, grab a strawberry 🍓, and let's get into it.

✨ SYNOPSIS ✨

typedef bool (*mongoc_client_session_with_transaction_cb_t) (
   mongoc_client_session_t *session,
   void *ctx,
   bson_t **reply,
   bson_error_t *error);

🌸 DESCRIPTION 🌸

So like. You hand this callback over to mongoc_client_session_with_transaction(), right? That's literally the whole deal 🫶.

The callback is where you run a sequence of operations that are meant to be contained within a transaction. That's your moment. Your main character energy 👑.

⚠️ but bestie, listen — the callback should not attempt to start or commit transactions. Not your job. The wrapper handles that. Stay in your lane, slay in your lane 💅.

🎀 PARAMETERS 🎀

  • session — a mongoc_client_session_t. Your session bestie for the ride 🌈.
  • ctx — a void* set to the user-provided ctx passed to mongoc_client_session_with_transaction(). It's your stuff, boomeranged right back to you 🪃.
  • reply — an optional location for a bson_t, or NULL. The callback should set this if it runs any operations against the server and receives replies. Got a reply? Park it here, icon ⭐.
  • error — a bson_error_t. The callback should set this if it receives any errors while running operations against the server. Errors happen, log 'em properly 😭.

🔥 RETURN 🔥

Returns true for success and false on failure. And ngl — if cb returns false then it should also set error. Like, don't just fail silently and dip, that's not the vibe 💀.
