xcb_randr_get_provider_info(3)

✨ xcb_randr_get_provider_info ✨

okay bestie, buckle UP 💖 this is xcb_randr_get_provider_info, a lil request from the xcb_randr crew (that's the XCB Requests manual, part of the X11 library family 🌸). It's giving "tell me everything about this display provider, pls and thank you" energy. Let's get into it 🫶

🌈 SYNOPSIS 🌈

First, the vibe-setter — you gotta pull in the header:

#include <xcb/randr.h>

🎀 Request function

xcb_randr_get_provider_info_cookie_t
xcb_randr_get_provider_info(xcb_connection_t *conn,
xcb_randr_provider_t provider, xcb_timestamp_t config_timestamp);

🦋 Reply datastructure

typedef struct xcb_randr_get_provider_info_reply_t {
    uint8_t         response_type;

🌟 DESCRIPTION 🌟

(yeah bestie, this section is literally empty in the original — we're not making stuff up, we're just vibing with the silence 🫶✨)

---

🌈 RETURN VALUE 🌈

You get back an xcb_randr_get_provider_info_cookie_t 🍪 — cute, right? But heads up: errors have to be handled when you call the reply function xcb_randr_get_provider_info_reply.

If you'd rather handle errors in the event loop instead, use xcb_randr_get_provider_info_unchecked. See xcb-requests(3) for the deets 👑

---

💀 ERRORS 💀

This request does never generate any errors. Not a single one. Zero. Clean slate. Iconic behavior honestly 🙈✨
