✨ es58x_fd_sizeof_rx_tx_msg ✨

okay bestie, welcome to the Kernel API Manual entry for es58x_fd_sizeof_rx_tx_msg — yes that's a mouthful, yes it's iconic, we move 💅

---

🌸 NAME 🌸

es58x_fd_sizeof_rx_tx_msg — literally just calculates the actual length of the structure of a rx or tx message. that's it. that's the whole job 🎀

---

🦋 SYNOPSIS 🦋

es58x_fd_sizeof_rx_tx_msg (msg );

---

💖 ARGUMENTS 💖

• msg — a message of variable length, and ngl it must have a dlc and a len field. no dlc/len, no vibe check passed, periodt 🫶

---

🌈 DESCRIPTION 🌈

okay so here's the tea ☕ — even though RTR frames actually have, like, no payload whatsoever, the ES58X devices still expect it. yes really. they want the length anyway. main character energy honestly 😭

and because of that, this thing must be a macro — not a function, a macro — so it can accept several types as an input, specifically struct es58x_fd_tx_can_msg and struct es58x_fd_rx_can_msg. flexible? we love to see it 💀✨

---

⭐ RETURN ⭐

the length of the message. that's the return value, bestie. go off 👑
