tty_kopen_shared(9)
π tty_kopen_shared β kernel API manual, section 9 π
okay so bestie, we're in the Kernel API Manual, section 9 (that's the kernel-functions girlies β¨), and today's main character is tty_kopen_shared. no cap, it's a whole vibe.
β¨ NAME β¨
tty_kopen_shared β open a tty device for shared in-kernel use π«Ά
πΈ SYNOPSIS πΈ
struct tty_struct * tty_kopen_shared (dev_t device );
π¦ ARGUMENTS π¦
deviceβ thedev_tof the device you wanna open. that's it, that's the whole argument, she's low maintenance π
π₯ DESCRIPTION π₯
So here's the tea β: it opens an already existing tty for in-kernel use. Like, the tty is already out here living its life, and you're just pulling up.
Compared to tty_kopen_exclusive above it, it doesn't ensure to be the only user. so like. no exclusive friendgroup energy here, everybody's welcome, it's giving open house π β¨
Locking: identical to tty_kopen above. same rules, same energy, no cap π
