device_property_read_bool(9)

💖 device_property_read_bool(9) 💖

ok so bestie, buckle up — this is a page from the Kernel API Manual, and it's literally about asking a device "hey, is this property a yes or a no?" 🎀

---

✨ NAME ✨

device_property_read_bool — returns the value for a boolean property of a device. that's it. that's the whole vibe. 🌸

---

🦋 SYNOPSIS 🦋

bool device_property_read_bool (const struct device *dev , const char *propname );

---

🎀 ARGUMENTS 🎀

• dev — the device whose property you're checking, bestie. the main character of this whole operation 💅
• propname — the name of the property. you gotta tell it which one you're asking about 🏷️

---

💫 DESCRIPTION 💫

ngl, the description here is short and sweet: use device_property_present to check for the property presence. that's literally the whole note 😭 — so like, if you're wondering whether the property is even there before you go asking what it says, device_property_present is your girl. 🫶

---

🔥 RETURN 🔥

it returns whether the property propname is true or false in the device firmware description. like, yes or no, binary, iconic behaviour ⭐
