xcb_present_query_version(3)

💅 xcb_present_query_version — the XCB Requests glow-up

okay bestie, so this one lives in the XCB Requests corner of the manual (that's xcb_present_query_version(3), if you're keeping receipts) and it's basically you asking the X server "hey girl, what version of the Present extension are we working with?" ✨

---

🌸 NAME 🌸

xcb_present_query_version — (yeah the original description is literally blank, she's mysterious like that, we love a mystery era 💖)

---

🎀 SYNOPSIS 🎀

#include <xcb/present.h>

✨ Request function ✨

xcb_present_query_version_cookie_t
       xcb_present_query_version(xcb_connection_t *conn,
       uint32_t major_version, uint32_t minor_version);

🦋 Reply datastructure 🦋

typedef struct xcb_present_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;

💜 Reply function 💜

xcb_present_query_version_reply_t
       *xcb_present_query_version_reply(xcb_connection_t *conn,
       xcb_present_query_version_cookie_t cookie,
       xcb_generic_error_t **e);

🍓 REQUEST ARGUMENTS 🍓

• conn — the XCB connection to X11. your lil hotline to the server, periodt 💅
• major_version — TODO: NOT YET DOCUMENTED. (yes bestie, the docs really do just say that, no cap, I'm not gatekeeping anything from you 😭)
• minor_version — TODO: NOT YET DOCUMENTED. (same energy, fr fr — the manpage left this one on read 🙈)

---

🌈 REPLY FIELDS 🌈

• response_type — the type of this reply, and in this case it's XCB_PRESENT_QUERY_VERSION. this field is also chillin' in the xcb_generic_reply_t, so you can use it to tell replies apart from each other. it's giving name tag at the party 🎀
• sequence — the sequence number of the last request processed by the X11 server. lowkey the server's "seen ✅" receipt.
• length — the length of the reply, in words (a word is 4 bytes). so do the math, bestie, 4 bytes per word, iconic units 🧚
• major_version — TODO: NOT YET DOCUMENTED. (again!! the manpage said "not yet" and then dipped 💀)
• minor_version — TODO: NOT YET DOCUMENTED. (truly a blank space era 🙈)

👑 DESCRIPTION 👑

...and that's it. there is literally nothing here. the original page left this section empty, and I'm not about to make stuff up for you, bestie — no invented lore in this group chat, that's the rule. ✨

---

⭐ RETURN VALUE ⭐

Returns an xcb_present_query_version_cookie_t. Errors have to be handled when calling the reply function xcb_present_query_version_reply.

If you'd rather handle errors in the event loop instead, use xcb_present_query_version_unchecked. See xcb-requests(3) for details. pick your fighter, both are valid 💅

---

💀 ERRORS 💀

This request does never generate any errors. zero drama, zero chaos, she's a calm queen, we love that for her 🫶

---

🔥 SEE ALSO 🔥

...nothing listed. the original page has the heading and then just moves on. so like, vibe with that. 🌸

and that's the whole page, bestie — every flag, field, and TODO preserved exactly as the original served it, no notes, no embellishment on the technical side 🎀

kisses, this was X Version 11, libxcb 1.17.0, on xcb_present_query_version(3) — slay, periodt, go query that version 💅✨
