tty_alloc_driver(9)

💅 tty_alloc_driver 💅

okay bestie, welcome to the Kernel API Manual page for tty_alloc_driver — the function whose whole job is literally allocate tty driver. no cap. 🎀

✨ SYNOPSIS ✨

the call is giving exactly this, character for character:

tty_alloc_driver (lines , flags );

💖 ARGUMENTS 💖

• lines — count of lines this driver can handle at most. yes, that's the limit, bestie. 💅
• flags — some of enum tty_driver_flag, will be set in driver->flags. periodt. ✨

🌈 RETURN 🌈

it returns a struct tty_driver or a PTR-encoded error (use IS_ERR and friends). 🫶

like, bestie, if it's an error, please actually check it with IS_ERR and friends — that's literally what the page says. 😭

🦋 SEE ALSO 🦋

• Kernel file ./include/linux/tty_driver.h — plus enum tty_driver_flag(9), struct tty_operations(9), and struct tty_driver(9). 👑
