okay so bestie, welcome to the Kernel API Manual, and today's main character is skb_copy_datagram_iter ✨ no cap, this one's a whole vibe.

🌸 NAME 🌸

skb_copy_datagram_iter — literally just copies a datagram into an iovec iterator. that's it. that's the whole job. 💅

✨ SYNOPSIS ✨

int skb_copy_datagram_iter (const struct sk_buff *skb , int offset ,
struct iov_iter *to , int len );

like, look at her. she's giving function signature realness 👑

🎀 ARGUMENTS 🎀

  • skb — the buffer you're copying from, bestie. this is the source of truth, the main character, the one with the data 💖
  • offset — where in the buffer to start copying from. not from the top, from here. got it? 🫶
  • to — the iovec iterator you're copying into. this is the destination, the receiving end, the "where it's all going" 🦋
  • len — how much data to copy from the buffer into the iovec. the amount. the quantity. the vibe check number 🔥
