💖 xcb_dbe_deallocate_back_buffer — from the XCB Requests manual (section 3) ✨

okay bestie, listen, we're doing some X11 double-buffering cleanup today and honestly? it's giving "tidying my room at 2am" energy but for back buffers 🎀

🌸 NAME 🌸

xcb_dbe_deallocate_back_buffer — deallocates a back buffer 💅

✨ SYNOPSIS ✨

#include <xcb/dbe.h>

🦋 Request function 🦋

xcb_void_cookie_t xcb_dbe_deallocate_back_buffer(xcb_connection_t *conn,
       xcb_dbe_back_buffer_t buffer);

💜 REQUEST ARGUMENTS 💜

  • conn — your XCB connection to X11, aka your little hotline to the server, periodt 🔥
  • buffer — the back buffer you want to deallocate. bye babe 🫶

🌈 DESCRIPTION 🌈

So basically, this deallocates the given buffer. that's the whole vibe.

but WAIT, there's lore 👀 — if buffer is an invalid id, a BadBuffer error is returned. and here's the part that matters most: because a window may have allocated multiple back buffer ids, the back buffer itself is not deleted until all these ids are deallocated by this call. it's not a "one and done" situation, it's a "wait for everyone to leave the group chat" situation 💀

👑 RETURN VALUE 👑

Returns an xcb_void_cookie_t. any errors (if any) have to be handled in the event loop, so don't come crying to the return value, she doesn't do that 💅

if you'd rather handle errors directly with xcb_request_check instead, use xcb_dbe_deallocate_back_buffer_checked. see xcb-requests(3) for the details, iykyk 📖

🎀 ERRORS 🎀

this request does never generate any errors. clean. flawless. no drama. ate. ✨
