dereference_hop(9)

💅 dereference_hop(9) 💅

okay bestie, welcome to the Kernel API Manual page for dereference_hop(9). This one is short and sweet, but the details are literally all here. No cap. 🫶

✨ NAME ✨

dereference_hop — converts a biased hop offset within a neighborhood to a pointer to the bucket it references. It’s giving “tiny lookup helper with main character energy.” 💖

🦋 SYNOPSIS 🦋

struct bucket * dereference_hop (struct bucket *neighborhood , unsigned
       int hop_offset );

🎀 ARGUMENTS 🎀

• neighborhood — the first bucket in the neighborhood. Like, the starting bucket of the whole little squad. 🪣✨
• hop_offset — the biased hop offset to the desired bucket. Yes bestie, it’s biased — that’s the whole vibe. 👑

🔥 RETURN 🔥

NULL if hop_offset is zero, otherwise a pointer to the bucket in the neighborhood at hop_offset - 1. So zero gives you NULL, and everything else gives you that bucket pointer. Periodt. 💀✨
