bitmap_and(9)

💖 bitmap_and(9) — Kernel API Manual 💖

okay so bestie, welcome to bitmap_and(9), a page straight out of the Kernel API Manual and honestly? it's giving "tiny function, huge main character energy" ✨

---

✨ NAME ✨

bitmap_and — Do logical and on bitmaps 🫶

like, that's it, that's the whole vibe. two bitmaps walk in, one bitmap walks out, and the operation between them is a logical and. iconic behavior, no notes. 💅

---

🌸 SYNOPSIS 🌸

bool bitmap_and (unsigned long *dst , const unsigned long *src1 , const unsigned long *src2 , unsigned int nbits );

not me presenting the signature in all its glory 😭 keep every space and comma exactly like that, she's fragile.

---

🎀 ARGUMENTS 🎀

• dst — the resulting bitmap 💖 this is where the answer goes, she's the output girlie, the destination, the final look.
• src1 — operand 1 🌸 first input bitmap, one half of the couple.
• src2 — operand 2 🦋 second input bitmap, the other half. yes they're being and-ed together, it's a whole love story.
• nbits — size of bitmap ⭐ literally how many bits we're dealing with. the whole scope of the operation, the vibe check in bit form.

ngl bestie, nbits is doing a lot of heavy lifting here — it's the size, so don't go feral and pass something mismatched. 🙈

🔥 SEE ALSO 🔥

• Kernel file ./tools/include/linux/bitmap.h 📁 — go read her, she's the source of truth for all your bitmap needs.
• bitmap_zalloc(9) 🧚 — the allocator sibling, zeroed and ready to slay.

and that's the whole page, bestie! 🌈 tiny, sweet, does exactly one (1) job and does it flawlessly. periodt. 👑
