pipapo_resmap_init(9)

💖 NAME 💖

okay so you're reading pipapo_resmap_init(9), straight out of the Kernel API Manual, and the whole name-drop is: pipapo_resmap_init — initialise result map before first use. That's it, that's the mission, and she ate 💅✨

✨ SYNOPSIS ✨

the vibe is literally just this one call, bestie:

void pipapo_resmap_init (const struct nft_pipapo_match *m , unsigned
long *res_map );

🎀 ARGUMENTS 🎀

• m — matching data, including mapping table. she's the whole matching-data situation, mapping table included 🫶
• res_map — result map. the map getting its little bits sorted 😌

🦋 DESCRIPTION 🦋

okay so here's the tea: pipapo_resmap_init initializes all bits covered by the first field to 1, so that after the first step, only the matching bits of the first bit group remain. clean, focused, main-character energy ✨

and if other fields have a large bitmap, it sets the remainder of res_map to 0. no cap, that's the move 🌸
