IIO_DEV_GUARD_CURRENT_MODE(9)

🎀 NAME 🎀

IIO_DEV_GUARD_CURRENT_MODE(9) from the Kernel API Manual is literally the function that acquires the mode lock with automatic release, bestie — cleanup-guard vibes only ✨💅.

---

✨ SYNOPSIS ✨

IIO_DEV_GUARD_CURRENT_MODE (dev );

---

🫶 ARGUMENTS 🫶

• dev — IIO device instance 🎀

---

🌸 DESCRIPTION 🌸

Okay so this one acquires the mode lock with cleanup guard semantics. It’s usually paired with iio_buffer_enabled 🦋.

⚠️ Real talk: this should not be used to protect internal driver state, and its use in general is strongly discouraged. Use any of the IIO_DEV_ACQUIRE_*_MODE variants, periodt 💀✨.

---

🦋 CONTEXT 🦋

Can sleep 😴💤.
