💖 cros_ec_pkt_xfer_rpmsg(9) 💖

okay so bestie, welcome to the Kernel API Manual — this is the page for cros_ec_pkt_xfer_rpmsg, and no cap, it's giving "send a packet, get a reply" energy 🎀

---

✨ NAME ✨

cros_ec_pkt_xfer_rpmsg — transfer a packet over rpmsg and receive the reply 🦋

---

🌸 SYNOPSIS 🌸

int cros_ec_pkt_xfer_rpmsg (struct cros_ec_device *ec_dev , struct
       cros_ec_command *ec_msg );

literally that's the whole vibe: two args in, an int out ✨

---

🎀 ARGUMENTS 🎀

• ec_dev — the ChromeOS EC device 💅 this is the main character, the device we're talking to
• ec_msg — the message to transfer 📨 like, the actual thing you're sending over

---

🔥 RETURN 🔥

on success it hands you back the number of bytes of the reply 👑 (slay), or a negative error code if things went sideways 😭

so like... if the number is negative, that's not a byte count, that's a sad — check it before you celebrate 🫶
