receive_n_bytes(9)

okay so bestie, welcome to receive_n_bytes(9) from the Kernel API Manual 💖 this one is short, sweet, and literally about receiving n bytes from the EC. no cap.

🌸 NAME 🌸

receive_n_bytes — receive n bytes from the EC. that's the whole job, icon ✨

✨ SYNOPSIS ✨

int receive_n_bytes (struct cros_ec_device *ec_dev , u8 *buf , int n );

look at that signature, it's giving kernel helper realness 💅

🎀 ARGUMENTS 🎀

• ec_dev — ChromeOS EC device. the EC device in question 🫶
• buf — Pointer to the buffer receiving the data. catch the data here 🎀
• n — Number of bytes received. the byte count, bestie 🔢

💅 DESCRIPTION 💅

Okay so the one thing to know: this function assumes buf is a pointer into the ec_dev->din buffer. that's the vibe. big assumption energy, so keep that in mind, iykyk 😭
