__vc_resize(9)

💅 __vc_resize(9) — like, the VT glow-up page 🎀

okay so real talk, we're in the Kernel API Manual today bestie, and the star of the show is __vc_resize(9). buckle up, she's a resize function and she ATE 💅

---

✨ NAME ✨

__vc_resize — resize a VT 🖥️✨

---

🦋 SYNOPSIS 🦋

int __vc_resize (struct vc_data *vc , unsigned int cols , unsigned int
rows , bool from_user );

literally just four args, no cap. look at her go 🌸

---

💖 ARGUMENTS 💖

• vc — the virtual console in question 🖥️ like, which one are we resizing, bestie
• cols — columns 📏
• rows — rows 📐
• from_user — invoked by a user? 🙈 (yes/no tea, bool style)

---

👑 DESCRIPTION 👑

so the vibe here is: resize a virtual console as seen from the console end of things. we're not out here doing our own thing — nope, we use the common vc_do_resize method to update the structures. teamwork makes the dream work fr fr 🫶✨

Locking 🔒: the caller must hold the console sem to protect console internals and vc->port.tty. not optional, not a suggestion, not "oops I forgot" energy. hold the sem or don't come to the party 💀
