netlbl_bitmap_walk(9)

🎀 netlbl_bitmap_walk(9) 🎀

okay bestie, welcome to the Kernel API Manual page for netlbl_bitmap_walk — it's giving “tiny utility function with main character energy” and honestly? iconic. 💅

---

✨ NAME ✨

netlbl_bitmap_walk — walk a bitmap looking for a bit 🦋

---

🌸 SYNOPSIS 🌸

int netlbl_bitmap_walk (const unsigned char *bitmap , u32 bitmap_len ,
       u32 offset , u8 state );

---

💖 ARGUMENTS 💖

• bitmap — the bitmap itself, bestie. the whole vibe. 🎀
• bitmap_len — length in bits, no cap.
• offset — starting offset, aka where you're sliding in at.
• state — if non-zero, look for a set (1) bit; else look for a cleared (0) bit. choose your fighter. ✨

---

🦋 DESCRIPTION 🦋

Starting at offset, walk the bitmap from left to right until either the desired bit is found or we reach the end. Return the bit offset, -1 if not found. literally that's it, and it ate. 💅
