💖 REQUEST ARGUMENTS 💖

• conn — the XCB connection to X11, aka ur lil hotline to the server. 📞
• crtc — TODO: NOT YET DOCUMENTED. (the manpage really said "figure it out bestie" 😭)

---

🌈 REPLY FIELDS 🌈

• response_type — the type of this reply, and in this case it's XCB_RANDR_GET_CRTC_GAMMA. it also lives inside the xcb_generic_reply_t, so you can use it to tell replies apart from each other. vibe check ur replies, basically. ✨
• sequence — the sequence number of the last request processed by the X11 server.
• length — the length of the reply, in words (and a word is 4 bytes, bestie — don't forget that part).
• size — TODO: NOT YET DOCUMENTED. 🙈

🫶 RETURN VALUE 🫶

Returns an xcb_randr_get_crtc_gamma_cookie_t. 🍪

Errors have to be handled when calling the reply function xcb_randr_get_crtc_gamma_reply.

If you want to handle errors in the event loop instead, use xcb_randr_get_crtc_gamma_unchecked. See xcb-requests(3) for details. ✨

and that's the whole page, bestie!! 💖 this was xcb_randr_get_crtc_gamma(3) from X Version 11, libxcb 1.17.0 — dated in the footer the same way it always was. go forth and read ur gamma ramps, you main character. 🌸✨🎀
