iio_validate_own_trigger(9)

💖 NAME 💖

iio_validate_own_trigger(9) — from the Kernel API Manual — is the lil function that checks if a trigger and an IIO device belong to the same device. Bestie, that’s the whole vibe. ✨

🎀 SYNOPSIS 🎀

int iio_validate_own_trigger (struct iio_dev *idev , struct iio_trigger *trig );

🦋 ARGUMENTS 🦋

• idev — the IIO device to check, no cap.
• trig — the IIO trigger to check, periodt.

🌸 DESCRIPTION 🌸

Okay so picture this: you have a trigger that can only be attached to its own device, and you need a validate_trigger callback. This function is literally built to be used as the validate_trigger callback for triggers that can only be attached to their own device. It’s giving “main character callback energy” and honestly? Obsessed. 💅

🔥 RETURN 🔥

• 0 — slay ✅ both the trigger and the IIO device belong to the same device.
• -EINVAL — not the same device, so that’s the result instead. 💀
