wilco_ec_mailbox(9)

wilco_ec_mailbox(9) from the Kernel API Manual — hiiii bestie, this is the Wilco EC mailbox page and she is lowkey the moment 👑✨

🎀 NAME 🎀

okay so wilco_ec_mailbox — send request to the EC and receive the response. That's it, that's the whole job, and it's giving very direct-communication icon behavior 💌

✨ SYNOPSIS ✨

int wilco_ec_mailbox (struct wilco_ec_device *ec , struct
wilco_ec_message *msg );

No cap, that's the exact signature up there — copy it, don't "fix" the spacing, she's built like that 🫶

💖 ARGUMENTS 💖

• ec — Wilco EC device. The EC device struct you're handing over, bestie 🎀
• msg — Wilco EC message. The message struct doing the request/response thing 💅

🔥 RETURN 🔥

Returns the number of bytes received, or a negative error code on failure. So if it's negative, that's a fail, not a vibe — check it, periodt 😭
