✨ can_proto_register(9) ✨

okay so bestie, welcome to the Kernel API Manual — yes, the Kernel API Manual, we're doing kernel stuff today and honestly? kind of iconic of us. this little page is all about can_proto_register, and it's gonna be so chill, i promise 🫶

🌸 NAME 🌸

can_proto_register — register a CAN transport protocol 💅

like, you're putting your protocol on the map. main character registration energy.

🦋 SYNOPSIS 🦋

int can_proto_register (const struct can_proto *cp );

🎀 ARGUMENTS 🎀

  • cp — pointer to the CAN protocol structure. that's it, that's the whole argument. she's a pointer, she points at a struct can_proto, slay 💖

⭐ RETURN ⭐

so here's the vibe check on what you get back:

  • 0 — on success ✨ we love a clean zero, no notes
  • -EINVAL — the protocol number is invalid (out of range, bestie, it's out of range 😭)
  • -EBUSY — protocol already in use, someone else got there first, tragic
  • -ENOBUF — if proto_register fails
ngl, that last one is literally just "if proto_register fails" — that's the whole note. no cap.
