xcb_xf86dri_query_version 💅

okay bestie, welcome to the xcb_xf86dri_query_version(3) page — it lives under the XCB Requests umbrella, and honestly? it's giving "short but iconic." we're asking the X server what version of the DRI (Direct Rendering Infrastructure) it's running. let's get into it ✨

NAME 🌈

xcb_xf86dri_query_version — that's literally it, the description slot is empty, the mystery is the moment 🎀

SYNOPSIS 🦋

first things first, you gotta pull in the header:

#include <xcb/xf86dri.h>

✨ Request function ✨

xcb_xf86dri_query_version_cookie_t
       xcb_xf86dri_query_version(xcb_connection_t *conn,

✨ Reply datastructure ✨

this is the lil struct you get back, and yes every field matters:

typedef struct xcb_xf86dri_query_version_reply_t {
    uint8_t  response_type;
    uint8_t  pad0;
    uint16_t sequence;
    uint32_t length;
    uint16_t dri_major_version;
    uint16_t dri_minor_version;
    uint32_t dri_minor_patch;
} xcb_xf86dri_query_version_reply_t;

✨ Reply function ✨

xcb_xf86dri_query_version_reply_t
       *xcb_xf86dri_query_version_reply(xcb_connection_t *conn,
       xcb_xf86dri_query_version_cookie_t cookie,
       xcb_generic_error_t **e);

REQUEST ARGUMENTS 🍓

  • conn — your XCB connection to X11. that's the whole list, bestie, she's low maintenance 💖

REPLY FIELDS 🧚

  • response_type — the type of this reply, which in this case is XCB_XF86DRI_QUERY_VERSION. this field also lives in the xcb_generic_reply_t, so you can use it to tell replies apart from each other. very "which one of y'all is this" energy 👑
  • sequence — the sequence number of the last request processed by the X11 server.
  • length — the length of the reply, in words (and a word here is 4 bytes, no cap).
  • dri_major_version — TODO: NOT YET DOCUMENTED. the lore is not yet written, we simply do not know 😭
  • dri_minor_version — TODO: NOT YET DOCUMENTED. same situation, the docs said "not today" 🙈
  • dri_minor_patch — TODO: NOT YET DOCUMENTED. and this one? also a mystery, iconic of it honestly 💀

DESCRIPTION 🌸

this section is literally empty in the source, so there's nothing to spill — no notes, no lore, just vibes ✨

RETURN VALUE 💜

returns an xcb_xf86dri_query_version_cookie_t. the way that errors work here is they have to be handled when you call the reply function xcb_xf86dri_query_version_reply.

and if you'd rather handle errors in the event loop instead, use xcb_xf86dri_query_version_unchecked — see xcb-requests(3) for the details, bestie, it's all in there 🫶

ERRORS 💀

this request does never generate any errors. not one. zero. slay, honestly 🎀
