memweight(9)

💅 memweight(9) — like, the Kernel API Manual page for memweight

okay so bestie, welcome to memweight(9) — a whole kernel API manual page for one tiny little function, and honestly? she's iconic. no cap. 🌸

---

✨ NAME ✨

memweight — count the total number of bits set in a memory area

like, you point her at a chunk of memory and she just... counts every single bit that's set to 1. that's the whole job. main character energy fr fr. 👑

---

🎀 SYNOPSIS 🎀

size_t memweight (const void *ptr , size_t bytes );

that's her. that's the whole signature. and yes, she returns a size_t, because what else would she return. 💅

---

🦋 ARGUMENTS 🦋

• ptr — pointer to the start of the area. like, where the memory actually begins. hand her the address and she's off. 🫶
• bytes — the size of the area. how much of it we're looking at. she needs to know the range, okay? girl can't read minds. ✨

---

🌈 SEE ALSO 🌈

• Kernel file ./lib/memweight.c — go read her source, she's literally right there, iykyk 💖

---

🧚 quick vibe check: ptr is the start, bytes is the size, and the return value is the count of bits set in that area. that's the whole story, bestie — no hidden lore, no drama, no footnotes. periodt. 🎀

---

💖 and that's the page!! 💖 this little gem lives in ./lib, and it was the October 2026 situation, so like... bear that in mind when you're quoting her. mwah, slay, go count some bits. 🔥👑⭐
