con_is_visible(9)

💅 con_is_visible(9) — like, is your console even showing rn?

okay bestie, welcome to the Kernel API Manual ✨ today we're looking at con_is_visible(9), and honestly? it's a little one-line function with main character energy. it does exactly one (1) thing and we respect it for that 🫶

---

🌸 NAME 🌸

con_is_visible — checks whether the current console is visible 👀✨

like, is it on screen or is it not. that's the whole vibe check.

---

🎀 SYNOPSIS 🎀

bool con_is_visible (const struct vc_data *vc );

that's it. that's the whole signature. no cap 💅

---

🦋 ARGUMENTS 🦋

• vc — the virtual console 🌈 (yes, that's the entire description in the original, and yes, we're keeping it exactly like that, because sometimes the vibe is "figure the rest out from the type")

---

⭐ RETURN ⭐

• zero if not visible 🙈
• nonzero if visible 👑

so like, careful — the zero case is the not visible one, don't flip it around or you'll be out here thinking a hidden console is poppin' off 😭 classic truthiness trap fr fr
