💖 xcb_sync_change_counter(3) 💖

okay bestie, so this is a page out of the XCB Requests manual, and it's all about the function xcb_sync_change_counter. The NAME section is honestly giving absolutely nothing — the description line is just blank, fr fr. Not a single word of summary. We move anyway. 🎀

✨ SYNOPSIS ✨

First you gotta pull in the header, like so:

#include <xcb/sync.h>

🦋 Request function

xcb_void_cookie_t xcb_sync_change_counter(xcb_connection_t *conn,
       xcb_sync_counter_t counter, xcb_sync_int64_t amount);

Look at that signature, it's literally iconic. 💅

🌸 REQUEST ARGUMENTS 🌸

  • conn — the XCB connection to X11. that's your link to the whole X situation, no cap.
  • counter — TODO: NOT YET DOCUMENTED. yeah bestie, the docs just didn't show up for this one 😭
  • amount — TODO: NOT YET DOCUMENTED. same energy. the manual left this blank, so I'm leaving it blank too. I do not make the rules. 🫶

💜 DESCRIPTION 💜

so... there is a DESCRIPTION heading, and underneath it there is nothing. empty. void. the description is not described. it's giving mystery. 🙈

⭐ RETURN VALUE ⭐

You get back an xcb_void_cookie_t. That's the deal. If there are any errors — if any, key word — you have to handle them in the event loop, because that's just how the cookie crumbles. 🍪

If you'd rather deal with errors directly using xcb_request_check instead, then you want xcb_sync_change_counter_checked. Peep xcb-requests(3) for all the deets on how that works. 💖

🎀 ERRORS 🎀

okay so good news for real: this request does never generate any errors. none. zero. clean slate. slay. ✨

🌈 SEE ALSO 🌈

...bestie. it's empty. there's a SEE ALSO heading and nothing under it. nothing to see here, literally. 💀
