__tty_alloc_driver(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

__tty_alloc_driver — allocate a tty driver. Yes bestie, this is the Kernel API Manual page for __tty_alloc_driver(9), and we are gonna get through it together ✨

🌸 SYNOPSIS 🌸

struct tty_driver * __tty_alloc_driver (unsigned int lines , struct
module *owner , unsigned long flags );

🎀 ARGUMENTS 🎀

  • lines — count of lines this driver can handle at most, like its absolute max capacity bestie 💅
  • owner — module which is responsible for this driver, the accountable icon 👑
  • flags — some of enum tty_driver_flag; they will be set in driver->flags ✨

🦋 DESCRIPTION 🦋

Okay so major heads-up, bestie: this should not be called directly. tty_alloc_driver should be used instead. That is the whole vibe. __tty_alloc_driver is not the one you call yourself, tty_alloc_driver is 🫶

✨ RETURN ✨

It gives you a struct tty_driver or a PTR-encoded error, so use IS_ERR and friends to check what you actually got. No cap 😭

🌈 SEE ALSO 🌈

Kernel file: ./drivers/tty/tty_io.c. And the related-pages group chat is literally right here, no skipping:

With all the love from the ./drivers/tty source tree, Kernel API Manual, dated October 2026, signed __tty_alloc_driver(9) 💖🫶✨
