MONGOC_SOCKET_ERRNO(3)

💅 MONGOC_SOCKET_ERRNO(3) — the libmongoc one ✨

okay so bestie, welcome to mongoc_socket_errno(3) from libmongoc — this is the little function that lets you peek at the errno your socket stashed away for you 💖

---

🌸 SYNOPSIS 🌸

int
mongoc_socket_errno (mongoc_socket_t *sock);

like, that's the whole flex. one function, one return value, zero drama ✨

---

🎀 PARAMETERS 🎀

• sock — A mongoc_socket_t. that's your socket, bestie, the main character of this whole operation 👑

---

🦋 DESCRIPTION 🦋

So here's the tea ☕: this function returns the currently captured errno for a socket. yep, the socket captured it — it's holding onto it for you 🫶

and why would you even care? lowkey genius reason: it's useful for checking what the last errno was after another function call has been made that clears the thread's errno variable 😭 because yes, that happens, and yes, it will absolutely ruin your whole detective era if you don't have a backup.

so this is your backup. your errno emergency contact 📞✨

---

⭐ RETURNS ⭐

• 0 if there is no error 🎉
• otherwise, a specific errno 🔥

that's it. no error = 0, error = the actual errno value. periodt 💅
