gnet_stats_start_copy(9)

💅 gnet_stats_start_copy — it's giving "let's dump some stats" ✨

okay so real talk, this page lives in the Kernel API Manual section 9 (that's the kernel API girlies, not your regular command-line besties) and honestly? she's a whole function and she ATE. let's get into it 🎀

---

🌸 NAME 🌸

gnet_stats_start_copy — start the dumping procedure in compatibility mode. yes bestie, compatibility mode — she's keeping it cute and backwards-friendly 🫶

---

✨ SYNOPSIS ✨

int gnet_stats_start_copy (struct sk_buff *skb , int type , spinlock_t
*lock , struct gnet_dump *d , int padattr );

like, five args, one int back, no cap. it's giving "simple but she has range" 💜

---

🦋 ARGUMENTS 🦋

• skb — the socket buffer you're putting your statistics TLVs into. it's the little container of destiny, ngl 📦
• type — the TLV type for the top level statistic TLV. like the big label on the outside of the box, ykwim?
• lock — the statistics lock 🔒 (yes you gotta grab it, we're being polite and thread-safe)
• d — your dumping handle. the main character of this whole operation honestly 👑
• padattr — the padding attribute. because alignment is self-care ✨

---

💖 DESCRIPTION 💖

so what she actually does: she initializes the dumping handle, grabs the statistic lock, and then appends an empty TLV header to the socket buffer so it can be used as a container for all the other statistic TLVs. like setting up the group chat before you add everyone to it, fr fr 📱💬

and then she tells you how it went: returns 0 on success, or -1 if the room in the socket buffer was not sufficient 😭 (buffer said "no vacancy", and honestly? valid).

⚠️ heads up bestie: check that return value. -1 means the socket buffer didn't have room, and pretending you didn't see it is not the vibe. 🙈
