for_each_console(9)

🌸 NAME 🌸

okay so this is the for_each_console(9) page from the Kernel API Manual, and the name is literally: Iterator over registered consoles. that’s the whole vibe: it walks the registered consoles, bestie. 💅

---

✨ SYNOPSIS ✨

here’s the synopsis, character for character:

for_each_console (con );

---

🎀 ARGUMENTS 🎀

• con — a struct console pointer used as the loop cursor. it’s the little “where am I rn” pointer for the loop, iykyk. 🦋

---

💖 DESCRIPTION 💖

okay so important thing: the console list and the console.flags are immutable while iterating. no cap, don’t be out here trying to change them mid-loop. 🙈

it also requires console_list_lock to be held. like, that lock is not optional, bestie. 🔒

💀 real talk: keep console_list_lock held, and remember the console list plus console.flags are immutable while you iterate. that’s the whole mood.
