tgafb_setcolreg(9)

🦋 NAME

tgafb_setcolreg — okay so this is an optional function bestie, and what it does is set a color register. That's it. That's the gig. 💅

✨ SYNOPSIS

int tgafb_setcolreg (unsigned regno , unsigned red , unsigned green ,
       unsigned blue , unsigned transp , struct fb_info *info );

🎀 ARGUMENTS

• regno — it's a boolean vibe: 0 means copy local, 1 means get_user function. Not me explaining booleans like they're lore, but here we are. 🙈
• red — the frame buffer colormap structure. Iconic. 🍓
• green — the green value, which can be up to 16 bits wide. Slay. 💚
• blue — the blue value, which can be up to 16 bits wide. Periodt. 💙
• transp — if supported, the alpha value, which can be up to 16 bits wide. Transparency is main character energy, fr fr. 🫶
• info — the frame buffer info structure. The blueprint, the moment, the whole situation. 👑

Lowkey important: this whole function is marked optional, so don't come for it if it's not there. It's giving "I'll show up if I feel like it." 💀
