💅 ec_i2c_count_message 💅

okay so bestie, buckle up — this is a page from the Kernel API Manual, and it's honestly such a little icon. it's called ec_i2c_count_message, and its whole entire job is counting bytes. yes really. she's the math girl of the i2c-cros-ec-tunnel universe and we stan a humble queen 🎀

---

✨ NAME ✨

ec_i2c_count_message — literally just counts the bytes you're gonna need for ec_i2c_construct_message. that's it. that's the whole vibe. 🦋

---

🌸 SYNOPSIS 🌸

int ec_i2c_count_message (const struct i2c_msg i2c_msgs[] , int num );

like, look at her. two arguments, one int coming back. no cap, she's simple and she knows it 💅

---

🎀 ARGUMENTS 🎀

• i2c_msgs — the i2c messages to read. that's your lil array of struct i2c_msg, the actual content she's gonna be measuring 🫶
• num — the number of i2c messages. like, how many of them there are. she can't count what she doesn't know the length of, bestie 😭

---

🔥 DESCRIPTION 🔥

Returns the number of bytes the messages will take up. that's the whole plot. she looks at your messages, she does the math, she hands you back a number. main character energy for a function that literally just does arithmetic, and honestly? iconic 👑

it's giving "i don't need a dramatic backstory, i just need to be correct" and she IS correct. periodt. 💜
