💖 xcb_x_print_print_query_version — bestie edition 💖

okay so we're doing xcb_x_print_p..._query_version(3) today, from the XCB Requests section of the manual. it's an X Print thing. yes, X Print. yes, it's a whole vibe. stay with me 🫶

✨ NAME ✨

xcb_x_print_print_query_version — (the original page literally leaves this blank, so like… it's giving mysterious. it queries the version, babe. that's the whole thing.)

🌸 SYNOPSIS 🌸

first you gotta pull in the header, no cap:

#include <xcb/xprint.h>

🎀 Request function

xcb_x_print_print_query_version_cookie_t
       xcb_x_print_print_query_version(xcb_connection_t *conn,

(yes the line really does end on that comma. that's just how she is. iconic behavior, we don't question it.)

🦋 Reply datastructure

typedef struct xcb_x_print_print_query_version_reply_t {
    uint8_t  response_type;
    uint8_t  pad0;
    uint16_t sequence;
    uint32_t length;
    uint16_t major_version;
    uint16_t minor_version;
} xcb_x_print_print_query_version_reply_t;

💜 Reply function

xcb_x_print_print_query_version_reply_t
       *xcb_x_print_print_query_version_reply(xcb_connection_t *conn,
       xcb_x_print_print_query_version_cookie_t cookie,
       xcb_generic_error_t **e);

👑 REQUEST ARGUMENTS 👑

  • conn — your XCB connection to X11. that's the link-up. the whole reason you're here. 💫

🌈 REPLY FIELDS 🌈

  • response_type — the type of this reply, and in this case it's XCB_X_PRINT_PRINT_QUERY_VERSION. this field is also chillin' in the xcb_generic_reply_t, so you can use it to tell replies apart from each other. like name tags at a party but for structs. 🏷️
  • sequence — the sequence number of the last request processed by the X11 server. keeping receipts, fr fr. 🧾
  • length — the length of the reply, in words. and bestie, a word is 4 bytes. don't forget. ✨
  • major_version — TODO: NOT YET DOCUMENTED. (not me documenting it. anyway.)
  • minor_version — TODO: NOT YET DOCUMENTED. (same energy, same silence.)

💅 DESCRIPTION 💅

the DESCRIPTION section of the original page is literally empty. nothing. void. a blank canvas. we respect her privacy. 🕳️✨

⭐ RETURN VALUE ⭐

she hands you back an xcb_x_print_print_query_version_cookie_t. 🍪 and listen — errors have to be handled when you call the reply function xcb_x_print_print_query_version_reply.

but if you'd rather handle errors in the event loop instead? use xcb_x_print_print_query_version_unchecked. see xcb-requests(3) for the details, because there are details. 📚

🚨 ERRORS 🚨

this request does never generate any errors. zero. none. clean sheet. no drama. 💀✨

🔥 SEE ALSO 🔥

this section is empty in the original. she said "no links today."

💖 AUTHOR 💖

Generated from xprint.xml. Contact xcb@lists.freedesktop.org for corrections and improvements. (they're literally asking for your notes, bestie, go off.)

and that's the whole page, mwah 💋 — this was X Version 11, libxcb 1.17.0, and we are so done here. slay, stay hydrated, and always read your reply fields. 🌸🦋💜
