tty_port_register_device(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

Hey bestie! Welcome to the Kernel API Manual, where we're talking about tty_port_register_device(9) today. Buckle up, because this is gonna be iconic πŸŽ€βœ¨


✨ NAME ✨

tty_port_register_device β€” register tty device, and honestly it's giving main character energy πŸ‘‘πŸ’…. No cap, this is the function you call when you need to register a tty device.


🌸 SYNOPSIS 🌸

struct device * tty_port_register_device (struct tty_port *port , struct
tty_driver *driver , unsigned index , struct device *device );

πŸŽ€ ARGUMENTS πŸŽ€

  • port β€” the tty_port of the device. This is literally the port, bestie. It's the main character of this whole operation πŸŽ€βœ¨
  • driver β€” the tty_driver for this device. Like, the driver that drives this device, obviously πŸš—πŸ’¨
  • index β€” the index of the tty. It's the number that tells you which tty you're talking about. Periodt πŸ”’πŸ‘‘
  • device β€” the parent if it exists, otherwise NULL. So if there's a parent device, you pass it here; if not, you pass NULL. Simple as that 🌸

πŸ’– DESCRIPTION πŸ’–

Okay so here's the tea β˜•: this function is literally the same as tty_register_device, except the port you provide gets linked to a concrete tty specified by index. That's the whole vibe, no cap.

Use this or tty_port_install (or both, go off πŸ‘‘). And if you're thinking about calling tty_port_link_device, save it for a last resort β€” like, only if you absolutely have to, bestie.

Last resort alert! Call tty_port_link_device as a last resort. Don't come for me, I'm just the messenger πŸ’€
