xcb_glx_get_color_table(3)

💅 xcb_glx_get_color_table — a lil' manual page, bestie

okay so this is a page from the xcb_glx fam (that's the XCB bindings to GLX, iykyk) 💖 — it lives in the xcb_glx_get_color_table(3) part of the manual, and honestly? it's giving "generated from XML and we didn't write a description." no cap.

✨ NAME ✨

xcb_glx_get_color_table — (and that's literally all the NAME section says, bestie, there's a whole dash and then nothing. iconic minimalism. 👑)

---

🌸 SYNOPSIS 🌸

First things first, you gotta include the header:

#include <xcb/glx.h>

🎀 Request function

xcb_glx_get_color_table_cookie_t
       xcb_glx_get_color_table(xcb_connection_t *conn,
       xcb_glx_context_tag_t context_tag, uint32_t target,
       uint32_t format, uint32_t type, uint8_t swap_bytes);

🦋 Reply datastructure

typedef struct xcb_glx_get_color_table_reply_t {
    uint8_t  response_type;
    uint8_t  pad0;
    uint16_t sequence;
    uint32_t length;
    uint8_t  pad1[8];
    int32_t  width;

💜 Reply function

xcb_glx_get_color_table_reply_t
       *xcb_glx_get_color_table_reply(xcb_connection_t *conn,

💖 REQUEST ARGUMENTS 💖

• conn — your XCB connection to X11. the whole vibe pipeline, fr fr.
• context_tag — TODO: NOT YET DOCUMENTED. yeah bestie, the docs said "we'll get to it" and then never did 😭
• target — TODO: NOT YET DOCUMENTED. mystery parameter, main character energy, zero backstory.
• format — TODO: NOT YET DOCUMENTED. we simply do not know.
• type — TODO: NOT YET DOCUMENTED. also a stranger to us.
• swap_bytes — TODO: NOT YET DOCUMENTED. even the byte-swapping is a secret. 💀

not me listing six args and four of them are literally TODO. the XCB docs really said "figure it out." 🙈

---

⭐ REPLY FIELDS ⭐

• response_type — the type of this reply, and in this case it's XCB_GLX_GET_COLOR_TABLE. this field also shows up in the xcb_generic_reply_t, so you can use it to tell replies apart from each other. it's like a little name tag at a party 🎀
• sequence — the sequence number of the last request processed by the X11 server. tracking numbers but for requests, obsessed.
• length — how long the reply is, in words. and yes bestie, a word here is 4 bytes. write that down.
• width — TODO: NOT YET DOCUMENTED. again!! the silence is loud. 😭

---

🫶 DESCRIPTION 🫶

...okay so the DESCRIPTION section is empty. nothing. void. a blank little space where the explanation should be. we are all just living in it. 💀

---

🔥 RETURN VALUE 🔥

You get back an xcb_glx_get_color_table_cookie_t — a whole cookie, slay 🍪. Errors? Those have to be handled when you call the reply function xcb_glx_get_color_table_reply.

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

---

🌸 ERRORS 🌸

This request does never generate any errors. no drama, no chaos, just peace and quiet ✨

---

🦋 SEE ALSO 🦋

(the original leaves this one blank too — bestie really said "you'll find your way.")

and that's the whole page, bestie!! 💅 this lil' slice of the manual is from X Version 11, shipping with libxcb 1.17.0 — so go forth, call your color table getter, and remember: four of those arguments are TODO and no one is coming to save us. mwah 💖🦋🎀
