STRUCT TEE_IOCTL_CLOSE_SESSION_ARG(9)

✨ NAME ✨

struct tee_ioctl_close_session_arg — bestie, this is the little struct that closes an open session 💅

okay so real talk, we're in the Kernel API Manual today (yes, section 9, the cool section), and this is the actual struct you hand over when you want a TEE session to wrap it up and go home. That's it. That's the whole job. She's small, she's focused, she's iconic. 🎀

🌸 SYNOPSIS 🌸

struct tee_ioctl_close_session_arg {
    __u32 session;
};

like, literally two lines of vibe. one field. no notes. 🔥

🧚 Members 🧚

• session — [in] the session id. that's your "which session are we closing" receipt, and you hand it in on the way in ✨

ngl this one's a short read and that's the point — know the struct, pass the id, close the session, move on. main character energy only 🌈

okay that's the whole page, ty for coming to my ted talk 💖 this lil guy lives over in ./include/uapi/linux and the docs are dated October 2026, so like… future-proofed bestie ⭐👑
