xcb_selinux_query_version(3)

✨ xcb_selinux_query_version ✨

okay bestie, welcome to the xcb_selinux_query_version page — section 3 of the manual, part of the XCB Requests crew 💖. This is the one where you ask the X server "hey girl, what version of the SELinux extension are you running?" and she replies with receipts. 🎀

---

🌸 SYNOPSIS 🌸

#include <xcb/xselinux.h>

🫶 Request function

xcb_selinux_query_version_cookie_t
       xcb_selinux_query_version(xcb_connection_t *conn,
       uint8_t client_major, uint8_t client_minor);

🦋 Reply datastructure

typedef struct xcb_selinux_query_version_reply_t {
    uint8_t  response_type;
    uint8_t  pad0;
    uint16_t sequence;
    uint32_t length;
    uint16_t server_major;
    uint16_t server_minor;
} xcb_selinux_query_version_reply_t;

💅 Reply function

xcb_selinux_query_version_reply_t
       *xcb_selinux_query_version_reply(xcb_connection_t *conn,
       xcb_selinux_query_version_cookie_t cookie,
       xcb_generic_error_t **e);

🌈 REQUEST ARGUMENTS 🌈

• conn — the XCB connection to X11, aka your direct line to the server, your hotline bling ☎️.
• client_major — TODO: NOT YET DOCUMENTED. yeah babe, the docs really said "mystery" on this one 💀 not me having nothing to tell you.
• client_minor — TODO: NOT YET DOCUMENTED. same energy, the lore is simply not written down yet 🙈.

---

💜 REPLY FIELDS 💜

• response_type — the type of this reply, and in this case it's XCB_SELINUX_QUERY_VERSION. 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 "which one of you is which" coded.
• sequence — the sequence number of the last request the X11 server processed. it's giving chronological order, fr fr ⭐.
• length — the length of the reply, measured in words (and a word here is 4 bytes, no cap) 📏.
• server_major — TODO: NOT YET DOCUMENTED. another one the writers left blank bestie 😭.
• server_minor — TODO: NOT YET DOCUMENTED. and that's the whole vibe for this one too 🍓.

🧚 DESCRIPTION 🧚

crickets ...yeah, this section is literally empty in the original. the description section said "no thoughts, head empty" 💀 nothing to add, nothing to invent, we respect the silence.

---

🔥 RETURN VALUE 🔥

It returns an xcb_selinux_query_version_cookie_t 🍪 — a whole cookie, iconic. Errors have to be handled when you call the reply function xcb_selinux_query_version_reply.

If you'd rather handle errors in the event loop instead, use xcb_selinux_query_version_unchecked — she's the unchecked girlie of the two 💅. See xcb-requests(3) for the details, iykyk.

---

💀 ERRORS 💀

This request does never generate any errors. not one. zero. she's unproblematic, main character energy only ✨.

---

👑 SEE ALSO 👑

nothing here either — the original left this one blank too, so we're keeping it blank, periodt 🎀.

and that's the whole page!! 🦋 this one came from X Version 11, libxcb 1.17.0, and it's the xcb_selinux_query_version(3) page — mwah, slay, go query some versions 💖✨
