STRUCT BINDER_REF_DATA(9)

✨ NAME ✨

okay bestie, welcome to struct binder_ref_data(9) — the Kernel API Manual page for, wait for it, binder_ref counts and id. no cap, that’s the whole vibe. 🎀

struct binder_ref_data — binder_ref counts and id

🦋 SYNOPSIS 🦋

the struct is literally giving:

struct binder_ref_data {
    int debug_id;
    uint32_t desc;
    int strong;
    int weak;
 };

🌸 Members 🌸

• debug_id — unique ID for the ref. its little name tag, fr fr 💅
• desc — unique userspace handle for ref. the handle bestie 🫶
• strong — strong ref count, but heads up: debugging only if not locked 😭
• weak — weak ref count, same energy: debugging only if not locked 💀

💖 Description 💖

okay so this structure exists to hold ref count and ref id information. since the actual ref can only be accessed with a lock, this structure is used to return information about the ref to callers of ref inc/dec functions. iconic little middleman behavior, honestly. ✨
