✨ xcb_glx_get_histogram ✨

okay bestie, welcome to the manual page for xcb_glx_get_histogram, a little request from the XCB Requests family (that's the manual section, iykyk). it lives in the glx world, it's giving "ask the X server for a histogram and get a cookie back" energy, and we're gonna walk through it together. no gatekeeping. 💖

🌸 NAME 🌸

xcb_glx_get_histogram — no description was ever written here, bestie, the manpage just leaves it blank and honestly? iconic of it

🦋 SYNOPSIS 🦋

First, include the header. you know the drill:

#include <xcb/glx.h>

💅 Request function

xcb_glx_get_histogram_cookie_t
       xcb_glx_get_histogram(xcb_connection_t *conn,
       xcb_glx_context_tag_t context_tag, uint32_t target,
       uint32_t format, uint32_t type, uint8_t swap_bytes,
       uint8_t reset);

🎀 Reply datastructure

typedef struct xcb_glx_get_histogram_reply_t {
    uint8_t  response_type;
    uint8_t  pad0;
    uint16_t sequence;
    uint32_t length;
    uint8_t  pad1[8];
    int32_t  width;
    uint8_t  pad2[12];
} xcb_glx_get_histogram_reply_t;

✨ Reply function

xcb_glx_get_histogram_reply_t
       *xcb_glx_get_histogram_reply(xcb_connection_t *conn,
       xcb_glx_get_histogram_cookie_t cookie, xcb_generic_error_t **e);

🧚 Reply accessors

uint8_t *xcb_glx_get_histogram_data(const
       xcb_glx_get_histogram_request_t *reply);

int xcb_glx_get_histogram_data_length(const
       xcb_glx_get_histogram_reply_t *reply);

xcb_generic_iterator_t xcb_glx_get_histogram_data_end(const
       xcb_glx_get_histogram_reply_t *reply);

💜 REQUEST ARGUMENTS 💜

  • conn — your XCB connection to X11. your whole link to the server, your ride or die. 🫶
  • context_tag — TODO: NOT YET DOCUMENTED. literally the manpage says nothing, bestie, we're all just vibing
  • target — TODO: NOT YET DOCUMENTED.
  • format — TODO: NOT YET DOCUMENTED.
  • type — TODO: NOT YET DOCUMENTED.
  • swap_bytes — TODO: NOT YET DOCUMENTED.
  • reset — TODO: NOT YET DOCUMENTED.

🌈 REPLY FIELDS 🌈

  • response_type — the type of this reply, and in this case it's XCB_GLX_GET_HISTOGRAM. this field is also chillin' in the xcb_generic_reply_t, so you can use it to tell your replies apart from each other. very "how do you do, fellow replies" of it. 😭
  • sequence — the sequence number of the last request the X11 server processed. the receipts, basically.
  • length — how long the reply is, in words. and just so we're clear: a word is 4 bytes. periodt.
  • width — TODO: NOT YET DOCUMENTED.

🍓 DESCRIPTION 🍓

there is literally nothing here. the section exists, it's empty, it's serving minimalism. we move.

💖 RETURN VALUE 💖

Returns an xcb_glx_get_histogram_cookie_t. 🍪

Errors have to be handled when you call the reply function, xcb_glx_get_histogram_reply.

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

🔥 ERRORS 🔥

this request does never generate any errors. not one. zero. clean sheet. slay. 💅

👑 SEE ALSO 👑

(nothing listed here, bestie — the section is there but it's empty, we respect the silence)

and that's the whole page, babe. this was X Version 11, libxcb 1.17.0, and it's the xcb_glx_get_histogram(3) manual. go forth and get those histograms. bye bestie! 💖✨🎀🦋🌸
