✨ REQUEST ARGUMENTS ✨

• conn — the XCB connection to X11. your lil hotline to the server, she's the main character fr 💅
• context_tag — TODO: NOT YET DOCUMENTED. yeah bestie, the docs simply did not show up to class that day 😭
• pname — TODO: NOT YET DOCUMENTED. same energy. not a single word. iconic honestly 💀

---

✨ REPLY FIELDS ✨

• response_type — the type of this reply, and in this case it's XCB_GLX_GET_DOUBLEV. this field also lives in the xcb_generic_reply_t, so you can use it to tell your replies apart from each other. it's giving name tag at a party 🏷️
• sequence — the sequence number of the last request processed by the X11 server. receipts, basically.
• length — the length of the reply, in words. and no, not vibes-words — a word here is 4 bytes. 📏
• n — TODO: NOT YET DOCUMENTED. 🙈
• datum — TODO: NOT YET DOCUMENTED. 🙈

✨ DESCRIPTION ✨

---

✨ RETURN VALUE ✨

Returns an xcb_glx_get_doublev_cookie_t. 🍪

heads up: errors have to be handled when you call the reply function xcb_glx_get_doublev_reply.

If you'd rather handle errors in the event loop instead, use xcb_glx_get_doublev_unchecked. see xcb-requests(3) for the deets. no cap. 🫶
