💅 tcx_setcolreg(9) — the Kernel API Manual, bestie edition 🎀

Okay so this one's from the Kernel API Manual, and it's literally the glow-up guide for tcx_setcolreg — an optional function that sets a color register. Obsessed. Let's get into it ✨

Six args, one int return, main character energy all around 🫶

🦋 ARGUMENTS 🦋

• regno — boolean, 0 copy local, 1 get_user function. Yep, that's what it says, we're just relaying the message 📋
• red — frame buffer colormap structure 🍓
• green — the green value, which can be up to 16 bits wide 💚
