ctucan_read_rx_frame(9)

✨ ctucan_read_rx_frame(9) ✨

okay so this is a page straight outta the Kernel API Manual and bestie, it's a whole little vibe — we're reading frames out of the RX FIFO 🎀

---

🌸 NAME 🌸

ctucan_read_rx_frame — literally reads a frame from the RX FIFO 💅

---

🦋 SYNOPSIS 🦋

void ctucan_read_rx_frame (struct ctucan_priv *priv , struct canfd_frame *cf , u32 ffw );

---

💖 ARGUMENTS 💖

• priv — a pointer to CTU CAN FD's private data, like its little personal diary 🫶
• cf — a pointer to the CAN frame struct, this is where the frame's gonna live
• ffw — the frame format word you already read earlier, no cap, you gotta hand it over

---

🌟 NOTE 🌟

bestie pls read the frame format word separately first and pass it in through 'ffw' — it does not come free with this function, iykyk 😭
