xcb_xkb_set_device_info(3)

✨ xcb_xkb_set_device_info ✨

okay bestie, welcome to another XCB Requests baddie: xcb_xkb_set_device_info(3). it's a whole request function, it lives in the XKB corner of libxcb, and it is genuinely here to set device info. no cap. 💖

---

🌸 NAME 🌸

xcb_xkb_set_device_info — and honestly? the upstream page left the description blank. like, empty. nothing. a lil dash and vibes. so that's what we're working with, bestie 💀 (we still love her)

---

🎀 SYNOPSIS 🎀

first things first, you gotta pull in the header:

#include <xcb/xkb.h>

✨ Request function ✨

xcb_void_cookie_t xcb_xkb_set_device_info(xcb_connection_t *conn,
       xcb_xkb_device_spec_t deviceSpec, uint8_t firstBtn,
       uint8_t nBtns, uint16_t change, uint16_t nDeviceLedFBs, const
       xcb_xkb_action_t *btnActions, const
       xcb_xkb_device_led_info_t *leds);

look at all those params. she's thorough. she's committed. periodt 💅

🦋 REQUEST ARGUMENTS 🦋

• conn — the XCB connection to X11. your whole lil link to the X server, the main character of every request, as always 💜
• deviceSpec — TODO: NOT YET DOCUMENTED. (the docs said "figure it out" and honestly same 🙈)
• firstBtn — TODO: NOT YET DOCUMENTED.
• nBtns — TODO: NOT YET DOCUMENTED.
• change — TODO: NOT YET DOCUMENTED.
• nDeviceLedFBs — TODO: NOT YET DOCUMENTED.
• btnActions — TODO: NOT YET DOCUMENTED.
• leds — TODO: NOT YET DOCUMENTED.

bestie, real talk: every single one of these is literally marked TODO: NOT YET DOCUMENTED. in the original. i'm not hiding anything from you — that is the documentation. iconic in a cursed way 🫶

---

💅 DESCRIPTION 💅

...it's empty. that's it. that's the section. the original has a DESCRIPTION heading and then absolutely nothing underneath it, and i refuse to invent lore that isn't there. we respect the mystery 😭✨

---

🌈 RETURN VALUE 🌈

she hands you back an xcb_void_cookie_t. and because it's a void cookie, any errors (if any even show up) have to be handled over in the event loop — that's just how the void girls do it.

if you'd rather deal with errors directly using xcb_request_check, then you want xcb_xkb_set_device_info_checked instead. slay, there's a checked twin for exactly this 💖

for the full tea, go read xcb-requests(3).

---

🔥 ERRORS 🔥

this request does never generate any errors. not one. zero. a peaceful, unbothered queen 👑

👑 SEE ALSO 👑

(blank. nothing listed. just empty space where the cross-references would be. we love a minimalist moment 🎀)

k that's the whole page, you absolutely ate this one. this lil rewrite is chillin' on X Version 11, running libxcb 1.17.0, and it's page xcb_xkb_set_device_info(3) — take care of her, mwah 💅💖✨
