get_tty_driver(9)

🎀 get_tty_driver(9) 🎀

Welcome to the Kernel API Manual, bestie! Today's main character is get_tty_driver(9), and she is here to find the device of a tty. Iconic behavior, honestly. 💅✨

🌸 NAME 🌸

get_tty_driver — find device of a tty. That's the whole job, no cap. 🫶

✨ SYNOPSIS ✨

struct tty_driver * get_tty_driver (dev_t device , int *index );

🫶 ARGUMENTS 🫶

• device — device identifier. It's the thing that tells you which device we're talking about. 💖
• index — returns the index of the tty. She hands that index right back to you, periodt. 🎀

💖 DESCRIPTION 💖

Okay so this routine returns a tty driver structure, given a device number, and also passes back the index number. That's it — that's the slay. 🌟

🔒 Locking: caller must hold tty_mutex. This is not a vibe check, bestie — the caller must hold it, fr fr.
