vt_resize(9)

🎀 NAME

vt_resize — resize a VT. Yep, that's the whole vibe, and this is the Kernel API Manual page for vt_resize(9), bestie. 💅

✨ SYNOPSIS

int vt_resize (struct tty_struct *tty , struct winsize *ws );

🦋 ARGUMENTS

• tty — the tty to resize. That's the terminal bestie getting the glow-up. 🫶
• ws — the winsize attributes. Basically the size tea. 📐

💖 DESCRIPTION

Okay so vt_resize resizes a virtual terminal. It gets called by the tty layer as we register our own handler for resizing — very main character of us, ngl. The mutual helper does all the actual work, so vt_resize is lowkey the pretty face of the operation. ✨

🔒 Locking: takes the console sem and the called methods then take the tty termios_rwsem and the tty ctrl.lock in that order. That order is not a suggestion, bestie — it's giving strict choreography. 💅
