🍓 REQUEST ARGUMENTS 🍓

• conn — the XCB connection to X11. your lil hotline to the server, bestie. 📞
• device_id — TODO: NOT YET DOCUMENTED. yeah. she's keeping secrets. no cap, the manpage literally just says that. 🙈

---

🌈 REPLY FIELDS 🌈

• response_type — the type of this reply, and in this case it's XCB_INPUT_GET_DEVICE_FOCUS. this field also lives in the xcb_generic_reply_t, so you can use it to tell your replies apart from each other. very "which one of y'all is this" energy. 🔥
• sequence — the sequence number of the last request the X11 server processed. her little timeline, her lore.
• length — the length of the reply, in words. and a word here is 4 bytes, iykyk. ⭐
• xi_reply_type — TODO: NOT YET DOCUMENTED.
• focus — TODO: NOT YET DOCUMENTED.
• time — TODO: NOT YET DOCUMENTED.
• revert_to — TODO: NOT YET DOCUMENTED.

not four fields in a row being undocumented 😭 the mystery is the aesthetic, i guess. we stan a cryptic icon.

🌟 DESCRIPTION 🌟

...nothing here. the section exists, it's just empty. main character silence. 🤫✨

---

💫 RETURN VALUE 💫

she hands you back an xcb_input_get_device_focus_cookie_t. 🍪 cute, right? but here's the thing — errors have to be handled when you call the reply function, xcb_input_get_device_focus_reply.

and if you'd rather handle errors in the event loop instead? use xcb_input_get_device_focus_unchecked. see xcb-requests(3) for the deets. 🫶

💀 ERRORS 💀

---

🧚 SEE ALSO 🧚
