💖 xcb_randr_query_version — the XCB Requests glow-up 💖

okay bestie, so this is a page from the XCB Requests manual set, and its whole name is xcb_randr_query_version(3). It's part of the RandR fam (that's "Resize and Rotate", the thing that lets your screens do their little layout thing). Let's get into it 💅

✨ NAME ✨

xcb_randr_query_version -

ngl the original page literally just leaves a lil dash here and nothing else. No description. We keep it real, so the dash stays 🫶

🌸 SYNOPSIS 🌸

#include <xcb/randr.h>

🎀 Request function

xcb_randr_query_version_cookie_t
       xcb_randr_query_version(xcb_connection_t *conn,
       uint32_t major_version, uint32_t minor_version);

🎀 Reply datastructure

typedef struct xcb_randr_query_version_reply_t {
           uint8_t  response_type;
           uint8_t  pad0;
           uint16_t sequence;
           uint32_t length;
           uint32_t major_version;
           uint32_t minor_version;
           uint8_t  pad1[16];
       } xcb_randr_query_version_reply_t;

🎀 Reply function

xcb_randr_query_version_reply_t
              *xcb_randr_query_version_reply(xcb_connection_t *conn,

              xcb_generic_error_t **e);

🦋 REQUEST ARGUMENTS 🦋

• conn — the XCB connection to X11. that's your lil phone line to the server, bestie 📞
• major_version — TODO: NOT YET DOCUMENTED. yeah. the page really said "we'll get to it". iconic of them tbh 😭
• minor_version — TODO: NOT YET DOCUMENTED. same energy. nobody wrote this part fr fr

---

⭐ REPLY FIELDS ⭐

• response_type — the type of this reply, and in this case it's XCB_RANDR_QUERY_VERSION. This field is also present in the xcb_generic_reply_t, so you can use it to tell replies apart from each other 👀
• sequence — the sequence number of the last request processed by the X11 server. it's giving "receipt number" 🧾
• length — the length of the reply, in words. and heads up: a word is 4 bytes in this house 💀
• major_version — TODO: NOT YET DOCUMENTED. again!! the mystery stays mysterious 🙈
• minor_version — TODO: NOT YET DOCUMENTED. and again. we love a cliffhanger ✨

💜 DESCRIPTION 💜

bestie. there is literally nothing here. the DESCRIPTION section is empty. no notes. slay, I guess 💅

---

🌈 RETURN VALUE 🌈

It hands you back an xcb_randr_query_version_cookie_t. That's your lil claim ticket, and errors have to be handled when you call the reply function xcb_randr_query_version_reply 🍓

But wait — if you'd rather handle errors inside the event loop instead, use xcb_randr_query_version_unchecked. See xcb-requests(3) for the deets ✨

👑 ERRORS 👑

This request does never generate any errors. Periodt. Zero drama, zero errors, it's just out here living its best life 🦋
