STRUCT OPTEE_MSG_PARAM_RMEM(9)

🎀 NAME 🎀

struct optee_msg_param_rmem is the registered memory reference parameter, bestie. That's the whole vibe — this page is from the Kernel API Manual (section 9), and it's giving "one very specific struct, explained with love." 💅

✨ SYNOPSIS ✨

Ok so the actual shape is right here — exact, no edits, no cap:

       struct optee_msg_param_rmem {
           u64 offs;
           u64 size;
           u64 shm_ref;
        };

• offs — offset into shared memory reference. yes bestie, that's the offset, periodt.
• size — size of the buffer. literally the buffer size, no extra lore.
• shm_ref — shared memory reference, pointer to a struct tee_shm. yes bestie, that's the pointer vibe.
