       uint32_t pname);

✨ REQUEST ARGUMENTS ✨

• conn — your XCB connection to X11. the whole vibe check with the X server goes through here, she's essential 💅
• context_tag — TODO: NOT YET DOCUMENTED. yeah bestie, the docs just said "we'll get to it", and they did not get to it 🙈
• target — TODO: NOT YET DOCUMENTED. same energy, still a mystery 🎀
• pname — TODO: NOT YET DOCUMENTED. three for three on the mystery box, iconic honestly 😭

---

✨ REPLY FIELDS ✨

• response_type — the type of this reply, which in this case is XCB_GLX_GET_COLOR_TABLE_PARAMETERIV. this field is also chillin' in the xcb_generic_reply_t, and it's literally how you tell your replies apart from each other, so like, use it 👑
• sequence — the sequence number of the last request the X11 server processed. it's giving receipt tracking 🧾✨
• length — the length of the reply, in words. and reminder that a word is 4 bytes, periodt 📏
• n — TODO: NOT YET DOCUMENTED. yeah. again. 💀
• datum — TODO: NOT YET DOCUMENTED. the last of the mystery squad 🦋

✨ DESCRIPTION ✨

so... the original page has absolutely nothing under this heading. no description. empty. a blank space. and honestly? we respect the minimalism 💜

---

✨ RETURN VALUE ✨

you get back an xcb_glx_get_color_table_parameteriv_cookie_t. 🍪 and bestie listen, errors do not come back here — you have to handle them when you call the reply function, xcb_glx_get_color_table_parameteriv_reply.

but if you'd rather handle your errors in the event loop instead? no stress, just use xcb_glx_get_color_table_parameteriv_unchecked. if you want the full tea on how that works, go read xcb-requests(3) 🫶

---

✨ ERRORS ✨

this request does never generate any errors. zero. none. a clean slate, a flawless queen 🌈

---

✨ SEE ALSO ✨

nothing here in the original, so nothing here from me either. a moment of silence 🤐
