💖 xcb_glx_get_mapfv — the XCB Requests glow-up 💖

okay so bestie, welcome to xcb_glx_get_mapfv(3), a lil slice of the XCB Requests manual family. It's a GLX map getter, it's giving "ask the X server for a float map and vibe," and yes we're gonna go through literally every single field together. grab a boba. 🧋✨

xcb_glx_get_mapfv —

(yeah bestie the description is literally empty in the source. not me leaving it blank too. the silence is iconic. 💅)

xcb_glx_get_mapfv_cookie_t xcb_glx_get_mapfv(xcb_connection_t *conn,
       xcb_glx_context_tag_t context_tag, uint32_t target,
       uint32_t query);

🔥 REQUEST ARGUMENTS 🔥

  • conn — the XCB connection to X11. your lil phone line to the server, bestie. 📞
  • context_tag — TODO: NOT YET DOCUMENTED. (the docs really said "mystery ✨")
  • target — TODO: NOT YET DOCUMENTED. (another mystery box, no cap)
  • query — TODO: NOT YET DOCUMENTED. (the third mystery box. it's giving unopened presents 🎁)

💫 REPLY FIELDS 💫

  • response_type — the type of this reply. in this case it's XCB_GLX_GET_MAPFV. this field also lives in xcb_generic_reply_t, so you can use it to tell your replies apart from each other. very "who dis" energy. 👀
  • sequence — the sequence number of the last request processed by the X11 server. it's the server's little receipt number. 🧾
  • length — the length of the reply, in words. heads up: a word is 4 bytes, that's the lore fr fr.
  • n — TODO: NOT YET DOCUMENTED. 🙈
  • datum — TODO: NOT YET DOCUMENTED. 😭

🌈 DESCRIPTION 🌈

...nothing. absolutely nothing. the DESCRIPTION section is empty. we love a mysterious queen who says nothing and still serves. 👑

🫶 RETURN VALUE 🫶

Returns an xcb_glx_get_mapfv_cookie_t. and listen — errors have to be handled when you call the reply function xcb_glx_get_mapfv_reply. that's the whole deal, bestie.

If you'd rather handle errors in the event loop instead, use xcb_glx_get_mapfv_unchecked. See xcb-requests(3) for details. pick your fighter. 💪

💀 ERRORS 💀

This request does never generate any errors.

bestie. it does NEVER generate errors. zero. none. not a single one. the drama-free icon we all aspire to be. ✨

👑 SEE ALSO 👑

(empty. the SEE ALSO section has no friends. it's giving lonely but unbothered. 💅)
