get_bool(9)

💖 get_bool — the Kernel API page, bestie edition 💖

okay so you're looking at get_bool(9) from the Kernel API Manual and honestly? it's a little cutie. tiny function, one job, does it well. let's get into it 🫶

---

✨ NAME ✨

get_bool — grab a parameter from the OF device. that's it. that's the whole vibe 🎀

---

✨ SYNOPSIS ✨

bool get_bool (struct platform_device *ofdev , const char *s );

like, look at her. two args, returns a bool. main character energy fr 🔥

---

✨ ARGUMENTS ✨

• ofdev — pointer to the OF device structure 💅 this is the device you're snooping around in
• s — the property you want retrieved. the thing you're looking up, iykyk 🌸

---

✨ DESCRIPTION ✨

so what does she actually do? get_bool goes looking for a property inside the device node, and if it finds that property, it hands you back the value. if it doesn't find it? you get 0. no drama, no error explosion, just a calm little 0 🙈

literally: property found → value. property not found → 0. periodt ⭐

---

✨ RETURN ✨

the value of the parameter if the parameter is found, or 0 otherwise. that's the whole contract, bestie, no cap 🦋
