xcb_composite...m_border_clip(3)

🦋 NAME 🦋

okay bestie, say hi to xcb_composite_create_region_from_border_clip 💖

that's it. that's the name. the description slot? literally empty. the manpage said nothing and honestly it meant it. no cap. 🙈

it lives in the XCB Requests corner of the manual, section 3, and the page header up top is truncating the name to xcb_composite...m_border_clip(3) because even man was like "girl this name is long" 💀

---

✨ SYNOPSIS ✨

first you gotta bring the header in, or nothing works:

#include <xcb/composite.h>

then, the request function herself 👑:

xcb_void_cookie_t
       xcb_composite_create_region_from_border_clip(xcb_connection_t *conn,
       xcb_xfixes_region_t region, xcb_window_t window);

she returns an xcb_void_cookie_t and takes three little besties. we'll meet them in a sec 🫶

---

🌸 REQUEST ARGUMENTS 🌸

• conn — the XCB connection to X11. your little lifeline to the server, the group chat you're actually sending messages in 💅
• region — TODO: NOT YET DOCUMENTED. yeah. the docs said "we'll do it later" and then never did. iconic behaviour, honestly 😭
• window — TODO: NOT YET DOCUMENTED. same energy. same void. no notes. 🙈

not me reading the docs hoping for lore and getting two TODOs in a trench coat 💀 i'm just the messenger bestie, i'm not gonna make stuff up for you.

---

🎀 DESCRIPTION 🎀

so… there isn't one. the DESCRIPTION section on this page is empty. completely. the way that the original manpage just has the heading and then absolute silence? it's giving "ghosted" 🫥

i'm not gonna invent lore that isn't there, so: nothing to see, moving on, periodt.

---

💜 RETURN VALUE 💜

she hands you back an xcb_void_cookie_t. that's the vibe. ✨

now listen, because this part matters: errors (if any) have to be handled in the event loop. like, you don't get them thrown at you immediately, you go collect them later like a little package at the front desk 📦

if you'd rather handle errors directly with xcb_request_check instead, then use xcb_composite_create_region_from_border_clip_checked — that's the checked version, she's the one who'll actually tell you what went wrong 🫶

and for all the details, go read xcb-requests(3). iykyk.

---

💀 ERRORS 💀

this request does never generate any errors. fr fr. she's a good girl, she causes no drama, zero chaos, no smoke 🌈

so if something IS breaking, bestie, it's not her. look elsewhere. 👀

---

🌈 SEE ALSO 🌈

nothing here either 😭 the SEE ALSO section is empty on this page — no references, no cross-links, just vibes and open space. so cute, so unhelpful, we move 💅
