STRUCT RC_MAP(9)

🎀 struct rc_map(9) 🎀

okay so this is the Kernel API Manual page for struct rc_map, and bestie, it literally just represents a keycode map table. that's the whole vibe. that's the NAME, that's the point. 💅 let's go ✨

✨ SYNOPSIS ✨

here's the whole struct, no cap, every field exactly where it lives:

struct rc_map {
    struct rc_map_table     *scan;
    unsigned int            size;
    unsigned int            len;
    unsigned int            alloc;
    enum rc_proto           rc_proto;
    const char              *name;
    spinlock_t lock;
 };

🌸 Members 🌸

okay so these are the members, one by one, we're going through all of them, no skipping 💖

• scan — pointer to struct rc_map_table. it's giving "here's where the actual table lives" energy.
• size — max number of entries. the ceiling. the limit. ✨
• len — number of entries that are in use. so like, size is how many chairs are in the room and len is how many are actually sat in 🫶
• alloc — size of can, in bytes. (yes the page literally says can there — not me, i'm just the messenger 💀 i'm keeping it exactly how it's written, that's the rule)
• rc_proto — type of the remote controller protocol, as defined at enum rc_proto. so the protocol flavour. iconic 👑
• name — name of the key map table. it's got a name. main character energy 🦋
• lock — lock to protect access to this structure. do NOT skip the lock, that's the whole point of it, thousand-percent 🙈

🔥 SEE ALSO 🔥

all the friends in this cinematic universe, in the kernel file ./include/media/rc-map.h:

• struct rc_map_table(9)
• struct rc_map_list(9)
• rc_map_register(9)
• rc_map_unregister(9)
• rc_map_get(9)

lowkey a warning that's just true: everything here lives in the kernel file ./include/media/rc-map.h, so that's where you go looking. 💜

okay that's the page!! 🍓 this one came from ./include/media and it's the October 2026 version, so that's the copyright/source date situation, and honestly? slay. go read the SEE ALSO section, periodt. 🧚✨🎀
