okay so bestie, welcome to the Library Functions Manual page for rte_mempool_objhdr(3) — yes that's the manual name, and yes we're gonna read the whole thing together, no skimming, I got you 🫶

🌸 NAME 🌸

rte_mempool_objhdr — the header struct that lives right in front of every single object in your mempool ✨

🎀 SYNOPSIS 🎀

#include <rte_mempool.h>

💅 Public Member Functions

  • RTE_STAILQ_ENTRY (rte_mempool_objhdr) next — the linked-list hook so your objects can chain together.

🍓 Data Fields

  • struct rte_mempool * mp — the mempool that owns this object. its home, its ride-or-die 💜
  • rte_iova_t iova — the IO address of the object 🔥

🦋 Detailed Description 🦋

It's a mempool object header structure, periodt. 💅

Every object stored in mempools is prefixed by this header structure — like, it literally sits in front of the object, main character positioning honestly 👑 — and it lets you do two iconic things: retrieve the mempool pointer straight from the object, and iterate over all the objects attached to a mempool. 🌈

When debug is enabled, a cookie is also added into this structure, preventing corruptions and double-frees. 🍪 not a snack cookie bestie, a safety cookie, and it is SO important, do not come for it.
