STRUCT FW_CDEV_EVENT_RESPONSE(9)

🎀 NAME 🎀

okay so bestie, this is struct fw_cdev_event_response(9) from the Kernel API Manual, and it is literally the struct that's Sent when a response packet was received. 💌✨

✨ SYNOPSIS ✨

struct fw_cdev_event_response {
    __u64 closure;
    __u32 type;
    __u32 rcode;
    __u32 length;
    __u32 data[];
};

🌸 Members 🌸

• closure — See fw_cdev_event_common; set by FW_CDEV_IOC_SEND_REQUEST or FW_CDEV_IOC_SEND_BROADCAST_REQUEST or FW_CDEV_IOC_SEND_STREAM_PACKET ioctl. 🫶
• type — See fw_cdev_event_common; always FW_CDEV_EVENT_RESPONSE. 💅
• rcode — Response code returned by the remote node. 📬
• length — Data length, i.e. the response's payload size in bytes. 📏
• data — Payload data, if any. 🍓

🦋 Description 🦋

Real talk: this event is sent instead of fw_cdev_event_response if the kernel or the client implements ABI version <= 5. 👀

It has the lack of time stamp field comparing to fw_cdev_event_response2. So yeah — no time stamp field here, that's the vibe. ⏳💀
