✨ bitmap_to_arr64(9) — a Kernel API Manual moment ✨

okay so bestie, welcome to the Kernel API Manual page for bitmap_to_arr64(9), and she is literally here to do one iconic thing: copy the contents of bitmap to a u64 array of bits. that's the vibe. no cap. 💅

🌸 NAME 🌸

bitmap_to_arr64 — copy the contents of bitmap to a u64 array of bits

✨ SYNOPSIS ✨

void bitmap_to_arr64 (u64 *buf , const unsigned long *bitmap , unsigned
       int nbits );

she's void in the synopsis, so there's no return value to babysit, bestie 🫶

🎀 ARGUMENTS 🎀

• buf — array of u64 (in host byte order), the dest bitmap. that's where the bits are going 💖
• bitmap — array of unsigned longs, the source bitmap. the original bit situation 🫶
• nbits — number of bits in bitmap. count 'em, don't guess 💅

🦋 SEE ALSO 🦋

okay the friend group is large, no cap. every one of these is invited to the group chat:
