XCB_SELINUX_GET_WINDOW_CREATE_CONTEXT_REPLY(3)

💖 xcb_selinux_get_window_create_context 💖

okay bestie, welcome to the xcb_selinux_get_window_create_context page — it's a section 3 (library function) situation, from the XCB Requests fam, and yes the name is a whole entire mouthful. we're gonna get through it together, hand in hand 🫶

---

✨ NAME ✨

xcb_selinux_get_window_create_context -

so like… the description is literally empty?? not me noticing that the dash just sits there with nothing after it 😭 it's giving mystery, it's giving "figure it out yourself," it's giving cryptic queen energy 👑

---

🌸 SYNOPSIS 🌸

first things first, you gotta pull in the header:

#include <xcb/xselinux.h>

🎀 Request function

xcb_selinux_get_window_create_context_cookie_t
       xcb_selinux_get_window_create_context(xcb_connection_t *conn,

(yeah the comma is just hanging there at the end, that's exactly how it is in the source, i don't make the rules 💅)

🎀 Reply datastructure

typedef struct xcb_selinux_get_window_create_context_reply_t {
    uint8_t  response_type;
    uint8_t  pad0;
    uint16_t sequence;
    uint32_t length;
    uint32_t context_len;
    uint8_t  pad1[20];
} xcb_selinux_get_window_create_context_reply_t;

look at her. so structured. so padded. pad1[20] is just vibing there holding space for the rest of the universe ⭐

🎀 Reply function

xcb_selinux_get_window_create_context_reply_t
       *xcb_selinux_get_window_create_context_reply(xcb_connection_t *conn,
       xcb_selinux_get_window_create_context_cookie_t cookie,
       xcb_generic_error_t **e);

🎀 Reply accessors

these are the little helpers that go dig around in the reply for you 🧚

char *xcb_selinux_get_window_create_context_context(const
       xcb_selinux_get_window_create_context_request_t *reply);

int xcb_selinux_get_window_create_context_context_length(const
       xcb_selinux_get_window_create_context_reply_t *reply);

xcb_generic_iterator_t
       xcb_selinux_get_window_create_context_context_end(const
       xcb_selinux_get_window_create_context_reply_t *reply);

🌈 REQUEST ARGUMENTS 🌈

• conn — it's your XCB connection to X11. your lil hotline to the server, your main character link-up 🔥

---

💜 REPLY FIELDS 💜

• response_type — the type of this reply, and in this specific case it's XCB_SELINUX_GET_WINDOW_CREATE_CONTEXT. this field is also chillin' inside xcb_generic_reply_t, which is the whole point — it's how you tell your replies apart from each other when they all show up at the function 💀
• sequence — the sequence number of the last request the X11 server actually processed. the receipts, basically 🧾
• length — how long the reply is, counted in words. and a word, bestie, is 4 bytes. write that down ✨
• context_len — TODO: NOT YET DOCUMENTED. yeah. she's undocumented. nobody wrote her lore yet 😭

🦋 DESCRIPTION 🦋

so… there's genuinely nothing here. the DESCRIPTION section is empty. not a single word. it's giving "the void stared back." honestly iconic of it 🌸

---

⭐ RETURN VALUE ⭐

you get back an xcb_selinux_get_window_create_context_cookie_t. cute, right? it's a cookie 🍪 but for a request, not a snack.

now listen — errors have to be handled when you call the reply function xcb_selinux_get_window_create_context_reply.

but if you'd rather handle your errors in the event loop instead? no problem, use xcb_selinux_get_window_create_context_unchecked. and if you want the full tea on how all that works, go read xcb-requests(3), it explains everything 📖

---

🎀 ERRORS 🎀

This request does never generate any errors.

fr fr. zero. none. not a single one. the drama-free request of your dreams 😌✨

---

👑 SEE ALSO 👑

nothing. empty. the SEE ALSO section has no references in it at all. it's just a lonely little heading waiting for friends that never came 🙈
