skb_pull_data(9)

💖 skb_pull_data(9) 💖

okay so welcome to the Kernel API Manual, bestie — this page is all about skb_pull_data(9), and it's giving "remove stuff from the front of the buffer" main character energy. no cap. 🫶

---

✨ NAME ✨

skb_pull_data — remove data from the start of a buffer returning its original position. literally that's the vibe check. 💅

---

💅 SYNOPSIS 💅

void * skb_pull_data (struct sk_buff *skb , size_t len );

---

🎀 ARGUMENTS 🎀

• skb — buffer to use. this is the skb bestie we're working with. 🦋
• len — amount of data to remove. yes, exactly that many. 🔥

---

🦋 DESCRIPTION 🦋

This function removes data from the start of a buffer, returning the memory to the headroom. iconic behavior, honestly. ✨

A pointer to the original data in the buffer is returned after checking if there is enough data to pull. so it does the vibe check first — very responsible of it. 💖

⚠️ bestie, plot twist: once the data has been pulled, future pushes will overwrite the old data. that's the tea. 😭
