tty_port_init(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

✨ tty_port_init(9) ✨

okay so we're in the Kernel API Manual today bestie, and the star of the show is tty_port_init πŸ’… buckle up.


🌸 NAME 🌸

tty_port_init β€” initialize tty_port

like, it initializes a tty_port. that's the whole vibe. no cap.


πŸ¦‹ SYNOPSIS πŸ¦‹

void tty_port_init (struct tty_port *port );

πŸŽ€ ARGUMENTS πŸŽ€

  • port β€” the tty_port you wanna initialize. that's it. that's the argument. she's simple, she's iconic 🫢

πŸ’– DESCRIPTION πŸ’–

So tty_port_init initializes the state of struct tty_port ✨ like it sets up the whole situation so your port is ready to be a main character.

But listen β€” this is the important part β€” once a port has been initialized using this function, you have to destroy the port by tty_port_destroy. you can't just leave it there, that's giving unfinished business 😭

and you've got options on how to do the destroying, bestie:

  • indirectly, by using tty_port refcounting (tty_port_put) β€” the chill, let-the-refcount-handle-it route πŸ’…
  • directly, if refcounting is not used β€” the do-it-yourself route 🫑

either way, the port gets destroyed. no skipping this step. periodt.
