    u32 op;
    u32 counts;
    union qcomtee_msg_arg args[];
};

🦋 Members 🦋

• result — the result of operation op on the object that cxt points at. like, how did it go? this is the receipt ✨
• cxt — the object ID, and it lives in the kernel. that's where the object is hosted, periodt 👑
• op — the operation being done on that object. what are we even doing here, y'know? 💅
• counts — the number of different types of arguments hanging out in args. not the total count, the types count, okay bestie don't get it twisted 🧚
• args — the array of arguments themselves. the whole squad 🌈
