thc_i2c_set_rx_max_size(9)

✨ thc_i2c_set_rx_max_size(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 — yes we're in kernel land today, and no, it's not scary, i promise. this one is literally a tiny little setter function and it's giving "short but iconic" 👑

---

🌸 NAME 🌸

thc_i2c_set_rx_max_size — set the I2C Rx transfer max input size, that's the whole vibe 🎀

---

🦋 SYNOPSIS 🦋

int thc_i2c_set_rx_max_size (struct thc_device *dev , u32 max_rx_size );

like look at her. one pointer, one u32, returns an int. minimalism ate 💅

---

🎀 ARGUMENTS 🎀

• dev — the pointer of the THC private device context, aka the little home base for your device, you gotta hand it over 🫶
• max_rx_size — max input report packet size for input report 📦 (yes, both of those words are "input report", no i'm not editing it, that's what it says, iykyk)

---

🔥 DESCRIPTION 🔥

so what does she do? she sets max_rx_size for the I2C RxDMA max input size control feature ✨ that's it. that's the whole description. no cap, sometimes a function is just a function and we respect the honesty 💀

like honestly? main character energy of a function that knows exactly what it wants and doesn't overexplain 🌈

---

⭐ RETURN ⭐

• 0 on success 🎉💖
• other error codes on failure 😭 (she's not gonna tell you which ones, that's a you problem bestie, check your code)

ngl, always check the return value. 0 is the slay outcome, anything else means something went sideways 🙈
