pipapo_base_sum(9)

🌸 pipapo_base_sum(9) — the Kernel API Manual bestie edition 🌸

okay so welcome to the Kernel API Manual page for pipapo_base_sum(9). This is the tiny helper that sums the step bit into a given len-sized netmask base, with carry included. It’s giving iconic little kernel-utility energy, and we are gonna read it together. 🫶

✨ NAME ✨

pipapo_base_sum — sums the step bit into a given len-sized netmask base, with carry. Lowkey a tiny arithmetic fairy doing netmask math. 🧚

📜 SYNOPSIS 📜

void pipapo_base_sum (u8 *base , int step , int len );

That’s the whole signature, bestie. void means it’s not handing you a return value back — it just does the thing. 💅

💅 ARGUMENTS 💅

• base — Netmask base. This is the netmask starting point the function works on. 🎀
• step — Step bit to sum. That’s the bit value getting summed in. ✨
• len — Netmask length, bytes. Yes, bytes, not vibes. 🍓
