iio_read_mount_matrix(9)

💅 iio_read_mount_matrix(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ we're literally in the iio_read_mount_matrix(9) page rn and it's giving "tiny function, huge friend group" 🎀

---

🌸 NAME 🌸

iio_read_mount_matrix — scoop up the iio device mounting matrix from the device's "mount-matrix" property 🫶

---

⭐ SYNOPSIS ⭐

int iio_read_mount_matrix (struct device *dev , struct iio_mount_matrix
*matrix );

no cap, that's the whole signature — two args, one int coming back at you 💖

---

🦋 ARGUMENTS 🦋

• dev — the device that the mounting matrix property is assigned to. it's the main character of this whole operation 👑
• matrix — where to store the retrieved matrix. like, this is the lil basket you're carrying the answer home in 🧺

---

✨ DESCRIPTION ✨

okay so here's the vibe check 🌈 if the device is assigned no mounting matrix property, then a default 3x3 identity matrix will be filled in. that's it, that's the whole personality. lowkey iconic, honestly 💅

---

🔥 RETURN 🔥

• 0 if success ✨
• or a negative error code on failure 😭
