rc_validate_scancode(9)

💅 NAME 💅

Hii bestie, welcome to the rc_validate_scancode(9) page in the Kernel API Manual ✨ This function is the vibe check for whether a scancode is valid for a protocol. And for nec, it should do the opposite of ir_nec_bytes_to_scancode() — yes, literally the opposite, no cap 🫶

🌸 SYNOPSIS 🌸

Behold the signature, iconic and exact:

bool rc_validate_scancode (enum rc_proto proto , u32 scancode );

🎀 ARGUMENTS 🎀

• proto — the protocol, bestie.
• scancode — the scancode. That’s the whole assignment 💅
