api_cmd(9)

💖 NAME

okay so this is api_cmd — the API CMD command, bestie. It lives in the Kernel API Manual and it’s giving “tiny kernel helper with main character energy” ✨ api_cmd(9) is literally right here to explain the vibe 🫶

✨ SYNOPSIS

int api_cmd (struct hinic_api_cmd_chain *chain , enum hinic_node_id dest
       , u8 *cmd , u16 cmd_size );

🎀 ARGUMENTS

• chain — the chain for the command, aka the whole lil setup carrying it 💅
• dest — destination node on the card that will receive the command. Slay, it knows where it’s going 📍
• cmd — command data, the actual payload vibe 💌
• cmd_size — the command size, aka how much data we’re working with 📏

🦋 DESCRIPTION

Return 0 - Success, negative - Failure. That’s the whole mood: 0 is the win, negative is the not-win 😭 no cap.
