💅 NAME 💅

okay so bestie, welcome to xcb_dbe_get_back_buffer_attributes — she gets back buffer attributes. that's the whole vibe. ✨

#include <xcb/dbe.h>

🎀 Request function

       xcb_dbe_get_back_buffer_attributes(xcb_connection_t *conn,
       xcb_dbe_back_buffer_t buffer);

🦋 Reply datastructure

this is the lil struct she hands back at you, no cap:

typedef struct xcb_dbe_get_back_buffer_attributes_reply_t {
    uint8_t                     response_type;
    uint8_t                     pad0;
    uint16_t                    sequence;
    uint32_t                    length;
    xcb_dbe_buffer_attributes_t attributes;

} xcb_dbe_get_back_buffer_attributes_reply_t;

🌸 Reply function

and here's how you actually go get the reply, bestie:

xcb_dbe_get_back_buffer_attributes_reply_t
       *xcb_dbe_get_back_buffer_attributes_reply(xcb_connection_t *conn,
       xcb_dbe_get_back_buffer_attributes_cookie_t cookie,
       xcb_generic_error_t **e);

👑 REQUEST ARGUMENTS 👑

• conn — your XCB connection to X11. the whole link-up, the group chat with the server, iykyk.
• buffer — the back buffer you're querying. the one you're curious about. main character of this request, fr fr.

🌈 REPLY FIELDS 🌈

• response_type — the type of this reply. in this case it's XCB_DBE_GET_BACK_BUFFER_ATTRIBUTES. this field also lives in the xcb_generic_reply_t, and it's literally how you tell your replies apart from each other. like name tags at a party but for packets. 💖
• sequence — the sequence number of the last request processed by the X11 server. her receipts, basically.
• length — the length of the reply, in words. and a word is 4 bytes, bestie, don't forget.
• attributes — TODO: NOT YET DOCUMENTED. yeah. she's a mystery. an enigma. we don't know her yet. 😭

💜 DESCRIPTION 💜

Returns the attributes of the specified buffer. that's it. that's the whole job. she's simple, she's effective, she slays. ✨

🔥 RETURN VALUE 🔥

She returns an xcb_dbe_get_back_buffer_attributes_cookie_t. and here's the thing — errors have to be handled when you call the reply function xcb_dbe_get_back_buffer_attributes_reply.

If you'd rather handle errors in the event loop instead, use xcb_dbe_get_back_buffer_attributes_unchecked. the details live over in xcb-requests(3), go peek. 🫶

💀 ERRORS 💀

This request does never generate any errors. not one. zero. she is unproblematic and we love that for her. 🙈
