xcb_glx_finish(3)

💅 xcb_glx_finish — the XCB Requests glow-up

okay bestie, so this is xcb_glx_finish(3), living its best life over in the XCB Requests section of the manual. she's a libxcb girlie. let's get into it 🫶

---

✨ NAME ✨

xcb_glx_finish — literally that's it, the name section is just vibes and the function name (the original has a lil dash and then nothing, and honestly? iconic. no notes.)

---

🦋 SYNOPSIS 🦋

first things first, you gotta pull in the header:

#include <xcb/glx.h>

🌸 Request function 🌸

xcb_glx_finish_cookie_t xcb_glx_finish(xcb_connection_t *conn,
       xcb_glx_context_tag_t context_tag);

🎀 Reply datastructure 🎀

this is the lil struct that comes back at you:

typedef struct xcb_glx_finish_reply_t {
    uint8_t  response_type;
    uint8_t  pad0;
    uint16_t sequence;
    uint32_t length;
} xcb_glx_finish_reply_t;

⭐ Reply function ⭐

and here's how you actually go get that reply:

xcb_glx_finish_reply_t *xcb_glx_finish_reply(xcb_connection_t *conn,
       xcb_glx_finish_cookie_t cookie, xcb_generic_error_t **e);

---

💜 REQUEST ARGUMENTS 💜

• conn — the XCB connection to X11. your lil phone line to the server, fr fr.
• context_tag — TODO: NOT YET DOCUMENTED. yeah bestie, the docs said "we'll finish this later" and then never did 😭 we simply do not know. moving on!

---

🌈 REPLY FIELDS 🌈

• response_type — what kind of reply this is. in this case it's XCB_GLX_FINISH. this field is also chillin' inside xcb_generic_reply_t, so you can use it to tell your replies apart from each other when you've got a whole pile of them.
• sequence — the sequence number of the last request the X11 server processed. it's giving "receipt number" energy 🧾
• length — how long the reply is, in words. and a word, bestie, is 4 bytes. remember that. it will come up.

👑 DESCRIPTION 👑

so… the original page's DESCRIPTION section is empty. like, genuinely empty. nothing. zero. a void. we're not making anything up here because that would be lying, and lying is not the move. so: it's blank, and that's canon. 🙈

---

🔥 RETURN VALUE 🔥

she returns an xcb_glx_finish_cookie_t. and listen — errors do NOT get handled here. you handle them when you call the reply function xcb_glx_finish_reply.

but if you'd rather handle your errors in the event loop instead? use xcb_glx_finish_unchecked for that. see xcb-requests(3) for the full tea. ☕

---

💀 ERRORS 💀

This request does never generate any errors.

that's right. no errors. not a single one. she's flawless. 💅✨

🍓 SEE ALSO 🍓

(the original lists nothing here, so… nothing here it is! consider this section a peaceful little meadow 🌸)
