xcb_dri2_query_version(3)

💖 xcb_dri2_query_version — the xcb_dri2_query_version(3) page, but make it cute 💖

okay so bestie, we're in the XCB Requests section of the manual and this lil guy is literally named xcb_dri2_query_version. that's it. that's the whole NAME entry, the description part is just blank — it's giving mysterious main character energy and honestly? we respect it. ✨

---

🌸 SYNOPSIS 🌸

first things first, you gotta pull in the header:

#include <xcb/dri2.h>

🎀 Request function

xcb_dri2_query_version_cookie_t
       xcb_dri2_query_version(xcb_connection_t *conn,
       uint32_t major_version, uint32_t minor_version);

🦋 Reply datastructure

typedef struct xcb_dri2_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;
} xcb_dri2_query_version_reply_t;

💅 Reply function

xcb_dri2_query_version_reply_t
       *xcb_dri2_query_version_reply(xcb_connection_t *conn,
       xcb_dri2_query_version_cookie_t cookie, xcb_generic_error_t **e);

✨ REQUEST ARGUMENTS ✨

• conn — your XCB connection to X11. the link-up, the group chat, the whole vibe. 🔗
• major_version — TODO: NOT YET DOCUMENTED. yeah bestie, the docs said "idk yet" and left it at that 🙈
• minor_version — TODO: NOT YET DOCUMENTED. same energy, same mystery, no cap 💀

---

🌈 REPLY FIELDS 🌈

• response_type — the type of this reply, which in this case is XCB_DRI2_QUERY_VERSION. this field also lives in the xcb_generic_reply_t, so you can use it to tell your replies apart from each other. it's the "which one of y'all texted me" field fr fr 👑
• sequence — the sequence number of the last request processed by the X11 server. your lil receipt number 🧾
• length — how long the reply is, measured in words — and heads up, one word is 4 bytes. so do the math, bestie 🍓
• major_version — TODO: NOT YET DOCUMENTED. iconic cryptic behaviour, we stan a blank slate ✨
• minor_version — TODO: NOT YET DOCUMENTED. truly said nothing and left 💀

💜 DESCRIPTION 💜

so… there's literally nothing here. the DESCRIPTION section is empty. not a single word. it's giving "showed up to the function, said nothing, served looks" and honestly, that's a mood. 🫶

---

⭐ RETURN VALUE ⭐

this one hands you back an xcb_dri2_query_version_cookie_t. and listen — errors do NOT get handled here. you handle them later, when you call the reply function xcb_dri2_query_version_reply. that's the deal, no shortcuts. 🎀

if you'd rather handle your errors inside the event loop instead, use xcb_dri2_query_version_unchecked. want the full tea on how that works? go read xcb-requests(3), it explains the details. 📚

---

💀 ERRORS 💀

this request never generates any errors. not a single one. flawless, unbothered, no drama, periodt. ✨

---

🔥 SEE ALSO 🔥

…yeah there's nothing listed here either. the section is just vibing, empty, alone, at peace. 🌙

💌 AUTHOR 💌

generated from dri2.xml. if you spot something wrong or wanna make it better, hit up xcb@lists.freedesktop.org — they take corrections and improvements. be nice, bestie, they're doing their best 🫶

and that's the whole page!! 💖 this gem came to you from X Version 11, running on libxcb 1.17.0 — so go forth, query your version, and slay. no date on this one, it's timeless, like you. 🌈👑✨
