STRUCT SDTX_BASE_INFO(9)

💖 struct sdtx_base_info(9) 💖

okay so bestie, welcome to the Kernel API Manual — this is literally the struct sdtx_base_info page and it's giving "tiny struct, big responsibilities". ✨

🌸 NAME 🌸

struct sdtx_base_info — describes if and what type of base is connected. that's it, that's the whole job, and it ate. 💅

---

✨ SYNOPSIS ✨

struct sdtx_base_info {
    __u16 state;
    __u16 base_id;
 };

two __u16 fields, zero drama, absolutely iconic. 🎀

• state — the state of the connection, aka the vibe check of your base. valid values are SDTX_BASE_DETACHED, SDTX_BASE_ATTACHED, and SDTX_DETACH_NOT_FEASIBLE (that last one is when a base is attached but a low clipboard battery prevents detachment — yes literally, the battery said "nope, not today" 😭). any other values are currently reserved, so don't come for them.
• base_id — the type of base connected. zero if no base is connected. that's the whole thing, fr fr — no base, no id. 🦋

bestie reminder: state has exactly those valid values and everything else is reserved, so please don't invent your own. no cap. 🫶
