💅 gnet_stats_finish_copy(9) 💅

okay so bestie, welcome to the Kernel API Manual — this page is all about gnet_stats_finish_copy(9), and it's literally the cleanup era of the dumping saga. ✨

---

✨ NAME ✨

gnet_stats_finish_copy — the function that finishes the dumping procedure. no cap, it's the final boss of the dump. 🎀

---

🎀 SYNOPSIS 🎀

int gnet_stats_finish_copy (struct gnet_dump *d );

---

🌸 ARGUMENTS 🌸

• d — the dumping handle. it's giving “hold my stats while I finish this.” 💅

---

✨ DESCRIPTION ✨

okay so here's the tea: gnet_stats_finish_copy corrects the length of the top level TLV so it includes all the TLVs that were added by gnet_stats_copy_XXX calls. 🫶

It also adds the backward compatibility TLVs if gnet_stats_start_copy_compat was used, and then it releases the statistics lock. iconic behavior, honestly. 🔥

Return value check, bestie: you get 0 on success. but if the room in the socket buffer was not sufficient, you get -1 with the statistic lock released. 😭 so yeah, -1 means no room and the lock is already out the door. 💀
