linear_range..._value_array(9)

💅 linear_range..._value_array(9) 💅

okay so welcome to the Kernel API Manual, bestie — this is the page for linear_range_get_value_array, and honestly? it's giving "small function, big main character energy" ✨

---

🌸 NAME 🌸

linear_range_get_value_array — fetch a value from array of ranges 🎀

like, you hand it a selector and it goes digging through a whole array of linear ranges to find the matching value. no cap. 💖

---

✨ SYNOPSIS ✨

int linear_range_get_value_array (const struct linear_range *r , int
ranges , unsigned int selector , unsigned int *val );

look at her. four params, one int coming back at you. iconic. 👑

---

🫶 ARGUMENTS 🫶

• r — pointer to array of linear ranges where value is looked from 🔍 (yes bestie, it's the array — the whole squad of ranges, not just one)
• ranges — amount of ranges in an array 🔢 (you gotta tell her how many are in the group chat or she's just guessing)
• selector — selector for which the value is searched 🎯 (this is the thing you're matching against)
• val — address where found value is updated 📬 (she writes the answer here, so pls give her a real address, not a vibe)

---

💜 DESCRIPTION 💜

Search through an array of ranges for value which matches given selector. 🕵️‍♀️✨

that's it, that's the whole gig. she walks the array, checks each range, and if the selector lines up she hands you back the value. simple, clean, slays. 💅

---

🔥 RETURN 🔥

• 0 on success 🎉 — we love a zero, zero means we ate
• -EINVAL given selector is not found from any of the ranges 😭 — yeah, if the selector isn't in any of the ranges, that's the error you get. not found = -EINVAL, periodt. 💀
