con_copy_unimap(9)

✨ con_copy_unimap — copy unimap between two vts ✨

okay so bestie, this one lives in the Kernel API Manual (section 9, kernel internals only, iykyk) and it's honestly such a mood: it literally just copies a unimap from one virtual terminal over to another. lowkey iconic. 💅

🌸 SYNOPSIS 🌸

int con_copy_unimap (struct vc_data *dst_vc , struct vc_data *src_vc );

🎀 ARGUMENTS 🎀

• dst_vc — the target 🎯 (where the unimap is going, bestie)
• src_vc — the source 🫶 (where the unimap is coming from)

💖 DESCRIPTION 💖

okay so the actual doing of the thing requires one very important vibe check first:

The caller must hold the console lock when invoking this method. no cap, no exceptions — grab that lock before you call this, fr fr.

That's literally the whole description and honestly? respect. short and slay. ✨

🦋 SEE ALSO 🦋

• Kernel file ./drivers/tty/vt/consolemap.c — the actual source, go read it 🧚
• struct uni_pagedict(9) — the struct involved, obsessed
• con_set_default_unimap(9) — the sibling function, also a main character

✨ that's the whole page, bestie ✨ it's from ./drivers/tty/vt and dated October 2026 — so like, future energy 🦋 thanks for reading, mwah 💋🎀
