xcb_xkb_use_extension(3)

✨ xcb_xkb_use_extension ✨

okay bestie, so this is a page from the XCB Requests corner of the manual — it's xcb_xkb_use_extension(3), and yes she's a libxcb girlie 💅. Basically you're sliding into the X11 server's DMs to ask "hey, do you speak the XKB extension, and which version, babe?" 🦋

---

🌸 NAME 🌸

xcb_xkb_use_extension —

(that's it. the NAME section literally has no description. mysterious. iconic. she said "no thoughts, head empty" 🙈)

---

✨ SYNOPSIS ✨

First things first, you gotta bring her in:

#include <xcb/xkb.h>

🎀 Request function

xcb_xkb_use_extension_cookie_t
       xcb_xkb_use_extension(xcb_connection_t *conn,
       uint16_t wantedMajor, uint16_t wantedMinor);

💖 Reply datastructure

typedef struct xcb_xkb_use_extension_reply_t {
    uint8_t  response_type;
    uint8_t  supported;
    uint16_t sequence;
    uint32_t length;
    uint16_t serverMajor;
    uint16_t serverMinor;
    uint8_t  pad0[20];
} xcb_xkb_use_extension_reply_t;

🦋 Reply function

xcb_xkb_use_extension_reply_t
       *xcb_xkb_use_extension_reply(xcb_connection_t *conn,
       xcb_xkb_use_extension_cookie_t cookie, xcb_generic_error_t **e);

---

💜 REQUEST ARGUMENTS 💜

• conn — the XCB connection to X11. your hotline to the server, your group chat with the display, the whole vibe 🔥
• wantedMajor — TODO: NOT YET DOCUMENTED. (ngl nobody wrote this one down, it's giving unfinished homework 😭)
• wantedMinor — TODO: NOT YET DOCUMENTED. (same energy, bestie, we simply do not know fr fr 💀)

---

🌈 REPLY FIELDS 🌈

• response_type — the type of this reply, which in this case is XCB_XKB_USE_EXTENSION. this field also lives inside xcb_generic_reply_t, so you can use it to tell your 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. it's the server's "last seen" timestamp, lowkey 📍
• length — the length of the reply, measured in words. and a word here is 4 bytes, periodt ✨
• supported — TODO: NOT YET DOCUMENTED. (undocumented, she's mysterious, we stan a cryptic queen 🙈)
• serverMajor — TODO: NOT YET DOCUMENTED. (also undocumented, no cap 💀)
• serverMinor — TODO: NOT YET DOCUMENTED. (yep, this one too, the docs said "not today" 😭)

---

🌟 DESCRIPTION 🌟

(there is literally nothing here. the DESCRIPTION section is empty. she's serving silence, and honestly? valid. main character energy 👑)

---

🫶 RETURN VALUE 🫶

She hands you back an xcb_xkb_use_extension_cookie_t. that's your lil receipt, your claim ticket, your "I'll be back for this" note 🎀

heads up bestie: errors have to be handled when you call the reply function xcb_xkb_use_extension_reply. don't just leave your cookie hanging, that's rude 💅

If you'd rather handle errors in the event loop instead, use xcb_xkb_use_extension_unchecked. See xcb-requests(3) for the deets 📚

---

💀 ERRORS 💀

This request does never generate any errors. not one. zero. she's unproblematic, she's drama-free, she's the friend who never starts anything 🌸✨

---

🔥 SEE ALSO 🔥

(empty, bestie. nothing to see here. go touch some grass, or like, go read xcb-requests(3) again 🦋)

and that's the whole page, bestie!! this lil icon came to you from X Version 11, running libxcb 1.17.0, and she's still rocking the xcb_xkb_use_extension(3) name tag 💖 thanks for reading all the way to the bottom, you're a real one — mwah, bye!! 🎀✨🦋
