tty_vhangup(9)

💖 tty_vhangup(9) 💖

okay bestie, welcome to the Kernel API Manual page for tty_vhangup(9) — yes, the vhangup one. Grab your iced coffee and let’s get into it 🫶✨

🌸 NAME 🌸

tty_vhangup — process vhangup

✨ SYNOPSIS ✨

void tty_vhangup (struct tty_struct *tty );

🎀 ARGUMENTS 🎀

• tty — the tty to hangup. That’s the one we’re saying bye to 💅

💅 DESCRIPTION 💅

Okay so the user has asked via a system call for the terminal to be hung up. We do this synchronously so that when the syscall returns, the process is complete. That guarantee is necessary for security reasons, fr fr — it’s giving “we are not being casual about this” 🔐✨

⚠️ Security girlie pop check: that synchronous guarantee is necessary for security reasons. Periodt. 🎀
