πŸ’« xcb_xc_misc_get_version πŸ’«

okay bestie, so this one lives in the XCB Requests section of the manual β€” like, it's xcb_xc_misc_get_version(3) if you're being formal, but we're on a first-name basis here 🫢. It's giving "let's ask the X server what version of the XC-MISC extension it's running" energy, and honestly? iconic.


✨ NAME ✨

xcb_xc_misc_get_version β€” and that's it, that's the whole description. the original literally just left a lil dash there like a girl who forgot to finish her sentence πŸ’€ no cap.


🌸 SYNOPSIS 🌸

First up, the include. yes you need it, don't be that girl:

#include <xcb/xc_misc.h>

πŸŽ€ Request function

xcb_xc_misc_get_version_cookie_t
xcb_xc_misc_get_version(xcb_connection_t *conn,
                        uint16_t client_major_version,
                        uint16_t client_minor_version);

πŸ¦‹ Reply datastructure

the whole lil struct, every field, exactly as it is:

typedef struct xcb_xc_misc_get_version_reply_t {
    uint8_t  response_type;
    uint8_t  pad0;
    uint16_t sequence;
    uint32_t length;
    uint16_t server_major_version;
    uint16_t server_minor_version;
} xcb_xc_misc_get_version_reply_t;

🌈 Reply function

xcb_xc_misc_get_version_reply_t
*xcb_xc_misc_get_version_reply(xcb_connection_t *conn,
                               xcb_xc_misc_get_version_cookie_t cookie,
                               xcb_generic_error_t **e);

πŸ’… REQUEST ARGUMENTS πŸ’…

  • conn β€” your XCB connection to X11. the main character of the whole operation, fr fr. everything goes through her.
  • client_major_version β€” TODO: NOT YET DOCUMENTED. like... the docs said "we'll get to it" and then never did 😭 that's the vibe, that's what we're working with.
  • client_minor_version β€” TODO: NOT YET DOCUMENTED. same energy bestie, nobody wrote this one either πŸ™ˆ

πŸ‘‘ REPLY FIELDS πŸ‘‘

  • response_type β€” what kind of reply this is, and in this specific case it's XCB_XC_MISC_GET_VERSION. plot twist: this field also lives in xcb_generic_reply_t, so you can use it to tell your replies apart from each other. very "hi, it's me" of it ✨
  • sequence β€” the sequence number of the last request the X11 server actually processed. it's like a lil receipt number 🧾
  • length β€” how long the reply is, measured in words. and a word, for the record, is 4 bytes. (yes, that kind of word. not the dictionary kind. stay with me πŸ’–)
  • server_major_version β€” TODO: NOT YET DOCUMENTED. she's a mystery, she's a legend, she's undocumented πŸ•΅οΈβ™€οΈ
  • server_minor_version β€” TODO: NOT YET DOCUMENTED. same, honestly. we simply don't know her.

🌟 DESCRIPTION 🌟

...nothing. blank. empty. the original has literally nothing under DESCRIPTION, which is so real of it. no thoughts, head empty, slay πŸ’€


🫢 RETURN VALUE 🫢

So it hands you back an xcb_xc_misc_get_version_cookie_t. and listen, errors? those have to be handled when you call the reply function xcb_xc_misc_get_version_reply. that's the deal, no skipping steps.

But if you'd rather handle errors in the event loop instead β€” lowkey valid β€” then use xcb_xc_misc_get_version_unchecked instead. and if you want the full tea, go read xcb-requests(3) for the details πŸ’œ


😭 ERRORS 😭

okay this is the good news section: this request does never generate any errors. not a single one. zero drama, zero chaos, she's an angel πŸŽ€ periodt.


πŸ’œ SEE ALSO πŸ’œ

...also empty bestie 😭 the original just left this one hanging. nothing listed. we move on.

and that's the whole page, bestie!! 🌈 the source was X Version 11 and libxcb 1.17.0, and this lil manual page is filed under xcb_xc_misc_get_version(3). go forth and query versions, you absolute icon πŸ‘‘πŸ’–
