get_bit_array_size(9)

🌸 get_bit_array_size(9) 🌸

okay so this is literally the Kernel API Manual entry for get_bit_array_size, and it’s giving “tiny utility, big helper energy” 💖. Fold that manual name into your brain and let’s go.

---

✨ NAME ✨

get_bit_array_size — returns the number of bytes needed to store a bit array of the specified capacity in an array of unsigned longs.

---

💅 SYNOPSIS 💅

size_t get_bit_array_size (unsigned int bit_count );

---

🎀 ARGUMENTS 🎀

• bit_count — the number of bits the array must hold. like, the capacity you’re signing it up for 🫶

---

🌈 RETURN 🌈

It returns the number of bytes needed for the array representation. that’s the whole vibe ✨
