✨ cros_ec_pd_command(9) ✨

okay so bestie, this is a page from the Kernel API Manual and it's lowkey one of those tiny-but-mighty functions you'll be glad you bookmarked. it's cros_ec_pd_command — the girl whose whole job is sending a command to the EC. that's it, that's the vibe. 💅

🎀 NAME 🎀

cros_ec_pd_command — send a command to the EC.

like, literally. she delivers your message to the embedded controller. main character energy, zero drama. 👑

🌸 SYNOPSIS 🌸

int cros_ec_pd_command (struct cros_ec_extcon_info *info , unsigned int
command , unsigned int version , void *outdata , unsigned int outsize ,
void *indata , unsigned int insize );

that signature is kinda long ngl, but she's worth it 🫶

🦋 ARGUMENTS 🦋

• info — pointer to struct cros_ec_extcon_info. this is the ✨context✨ she's working with, so don't be out here passing nonsense.
• command — the EC command. the actual thing you're asking for, iykyk.
• version — the EC command version. yes, she's versioned, she's professional.
• outdata — EC command output data. this is where the goodies land 💖
• outsize — size of outdata. tell her how big the landing pad is, bestie.
• indata — EC command input data. what you're feeding her 🍓
• insize — size of indata. same deal, but for the input side.

no cap: outdata/outsize and indata/insize are a matched set — one without the other is giving chaos. 🙈
