• response_type — the type of this reply, in this case XCB_RANDR_GET_OUTPUT_INFO. This field is also present in the xcb_generic_reply_t and can be used to tell replies apart from each other 💅 it's the little name tag at the party
• sequence — the sequence number of the last request processed by the X11 server 🔢
• length — the length of the reply, in words (a word is 4 bytes) 📏

🔥 RETURN VALUE 🔥

Returns an xcb_randr_get_output_info_cookie_t 🍪 (yes, a cookie — you grab it now and cash it in later, main character energy).

Errors have to be handled when calling the reply function xcb_randr_get_output_info_reply.

If you'd rather handle errors in the event loop instead, use xcb_randr_get_output_info_unchecked. See xcb-requests(3) for details 👀
