xcb_shm_completion_event_t(3)

✨ xcb_shm_completion_event_t ✨

okay bestie, welcome to the xcb_shm_completion_event_t page 💖 this is one of the XCB Events girlies, and honestly? she's giving "your shared memory upload finished, congrats queen" 🎀

🌸 NAME 🌸

xcb_shm_completion_event_t — the event that reports your XCB_SHM_PUT_IMAGE request has completed 🫶 no cap, that's literally her whole job.

🦋 SYNOPSIS 🦋

#include <xcb/shm.h>

💅 Event datastructure 💅

ok so here's the whole struct, character for character, do NOT freestyle on this:

typedef struct xcb_shm_completion_event_t {
    uint8_t        response_type;
    uint8_t        pad0;
    uint16_t       sequence;
    xcb_drawable_t drawable;
    uint16_t       minor_event;
    uint8_t        major_event;
    uint8_t        pad1;
    xcb_shm_seg_t  shmseg;
    uint32_t       offset;
} xcb_shm_completion_event_t;

👑 EVENT FIELDS 👑

every single field, explained, because we do not gatekeep here:

• response_type — the type of this event, and in this case it's XCB_SHM_COMPLETION. this field also lives in the xcb_generic_event_t, so you can use it to tell your events apart from each other. it's giving name tag at a party 🎀
• sequence — the sequence number of the last request the X11 server processed. the receipts, basically 🧾
• drawable — the drawable that got used in the XCB_SHM_PUT_IMAGE request. main character of the image, tbh 🖼️
• minor_event — the minor opcode used in the request. it's always XCB_SHM_PUT_IMAGE, every single time, no exceptions ✨
• major_event — the major opcode used in the request. it's always the opcode of the MIT-SHM extension. periodt 💅
• shmseg — the shared memory segment that got used in the request 🍓
• offset — the offset in that shared memory segment that got used in the request. yes, the little positional detail, we love her 🙈

💖 DESCRIPTION 💖

the X server generates this one to report that an XCB_SHM_PUT_IMAGE request has been successfully processed. that's it, that's the tea — a lil confirmation notification, from the server to you, because she's thoughtful like that 🌈
