MONGOC_URI_SET_USERNAME(3)

💅 MONGOC_URI_SET_USERNAME(3) 💅

okay bestie, so this is a page from the libmongoc manual, and it's about one tiny little function that does exactly one tiny little thing: it slaps a username onto a URI you already parsed. that's it. that's the whole vibe. let's get into it 🎀

---

✨ SYNOPSIS ✨

bool
mongoc_uri_set_username (mongoc_uri_t *uri, const char *username);

look at her. two args, returns a bool. she's small but she's doing something, okay? 👑

---

🌸 PARAMETERS 🌸

• uri — A mongoc_uri_t. like, the URI object itself, the one you already have sitting there. this is the thing getting a glow-up.
• username — The new username. the const char * in question. literally the name you want to set. 🫶

---

🦋 DESCRIPTION 🦋

so here's the tea: this function sets the URI's username, but specifically after the URI has already been parsed from a string. like, the parsing party already happened, and now you're going back in to edit the guest list. 💅

and why do we care? because the driver authenticates with this username if the password is also set. so the username alone is giving "name tag at a party" — you need the password too for the actual auth to go down. iykyk. 🔥

---

⭐ RETURNS ⭐

Returns false if the option cannot be set — for example, if username is not valid UTF-8. 😭 so yeah, if your string is cursed encoding-wise, she will simply say no. respect her boundaries. 🙈
