🫶 REQUEST ARGUMENTS 🫶

• conn — your connection to X11, the little string that keeps you and the server connected, no cap. 💫
• context_tag — TODO: NOT YET DOCUMENTED. yeah bestie the docs ghosted us on this one 😭
• map — TODO: NOT YET DOCUMENTED. also a mystery, also iconic for it 🕵️♀️

---

👑 REPLY FIELDS 👑

• response_type — the type of this reply, and in this case it's XCB_GLX_GET_PIXEL_MAPUSV. this field is also chillin' in the xcb_generic_reply_t, so you can use it to tell replies apart from each other. vibe check passed ✅
• sequence — the sequence number of the last request the X11 server processed. like a lil receipt number for your request 🧾
• length — how long the reply is, in words (and heads up, a word is 4 bytes here, not vibes). 📏
• n — TODO: NOT YET DOCUMENTED. 💀
• datum — TODO: NOT YET DOCUMENTED. 💀

💖 DESCRIPTION 💖

so... the DESCRIPTION section is literally empty. nothing. a void. the manual page said "no thoughts, head empty" 🕳️✨

we're respecting her silence, periodt.

---

⭐ RETURN VALUE ⭐

She returns an xcb_glx_get_pixel_mapusv_cookie_t, bestie. and listen — errors have to be handled when you call the reply function xcb_glx_get_pixel_mapusv_reply. that's the moment of truth, that's the main character scene.

If you'd rather handle errors in the event loop instead, use xcb_glx_get_pixel_mapusv_unchecked. See xcb-requests(3) for details — she explains the whole cookie situation better than I ever could 🫶

🔥 ERRORS 🔥

This request does never generate any errors. not one. she is unbothered, moisturized, in her lane, focused, flourishing. 💅

no cap, zero errors. that's just how she is.

🦋 SEE ALSO 🦋

...the SEE ALSO section is empty too. she's mysterious. she's keeping her secrets. iykyk 🙈
