iptfs_skb_prepare_frag_walk(9)

🎀 NAME 🎀

iptfs_skb_prepare_frag_walk — initialize a frag walk over an skb.

Okay bestie, you're on the iptfs_skb_prepare_frag_walk(9) page from the Kernel API Manual, and it's literally here to help you initialize a frag walk over an skb. That's the whole assignment. Slay. 💅

✨ SYNOPSIS ✨

void iptfs_skb_prepare_frag_walk (struct sk_buff *skb , u32
       initial_offset , struct iptfs_skb_frag_walk *walk );

🌸 ARGUMENTS 🌸

• skb — the skb to walk. That's the little guy you're walking through, no cap.
• initial_offset — start the walk initial_offset into the skb. Yes, literally that far in.
• walk — the walk to initialize. This is the one getting set up, bestie.

🦋 DESCRIPTION 🦋

Okay so here's the heads-up: future calls to skb_add_frags will expect the offset value to be at least initial_offset large. That's the rule, fr fr. 🌈
