tee_client_cancel_req(9)

💖 NAME 💖

okay so this is tee_client_cancel_req(9) from the Kernel API Manual 💅 and it is literally about requesting cancellation of the previous open-session or invoke-command operations in a Trusted Application. no cap, that's the whole name-vibe, bestie.

✨ SYNOPSIS ✨

the signature goes like this, copy it exactly or the compiler will side-eye you:

int tee_client_cancel_req (struct tee_context *ctx , struct
tee_ioctl_cancel_arg *arg );

🎀 ARGUMENTS 🎀

• ctx — TEE Context. that's your context, bestie, hold onto it 🫶
• arg — Cancellation arguments, see description of struct tee_ioctl_cancel_arg. iykyk, the struct has the lore 💅

🦋 DESCRIPTION 🦋

the return vibe check is: it returns < 0 on error else 0 if the cancellation was successfully requested. that's it, no extra lore, periodt ✨
