STRUCT LIVEUPDATE_SESSION_GET_NAME(9)

💖 NAME 💖

okay so bestie, this is struct liveupdate_session_get_name — the struct that goes with ioctl(LIVEUPDATE_SESSION_GET_NAME). Yes, that's the whole name. Iconic.

✨ SYNOPSIS ✨

       struct liveupdate_session_get_name {
           __u32 size;
           __u32 reserved;
           __u8 name[LIVEUPDATE_SESSION_NAME_LENGTH];
        };

🎀 Members 🎀

• size — input, bestie: this one is sizeof(struct liveupdate_session_get_name). Literally the size of the struct itself, no cap.
• reserved — input, and it must be zero. It's reserved for future use, so leave it alone. 🫶
• name — output: a null-terminated string with the full session name. Full name, full slay. ✨

💅 Description 💅

So this ioctl retrieves the full name of the session associated with this file descriptor. The whole reason it exists? The kernel may truncate the name shown in /proc, and that is lowkey annoying, so this gives you the full thing. 👑

🔥 Return 🔥

0 on success, negative error code on failure. That's it. Simple. Gorgeous. 💅
