nvme_fdp_re...andle_update(2)

✨ NAME ✨

nvme_fdp_reclaim_unit_handle_update — bestie, this one updates a whole list of reclaim unit handles 💅

It's part of the libnvme API manual, and honestly? She's niche but she works.

---

🌸 SYNOPSIS 🌸

int nvme_fdp_reclaim_unit_handle_update (int fd , __u32 nsid , unsigned
       int npids , __u16 *pids );

Look at her. Four little params and she's off doing her thing 🦋

---

🎀 ARGUMENTS 🎀

• fd — the file descriptor of the nvme device. like, your way in to the device, no cap. 🔑
• nsid — the namespace identifier. which namespace are we talking to? this one. be specific bestie.
• npids — number of placement identifiers. literally just how many pids are in the list, count them.
• pids — a list of placement identifiers. this is the actual list of reclaim unit handles getting updated. she's a pointer to __u16 so she's bringing the whole crew 🫶

---

💖 RETURN 💖

So here's the tea ☕ — it returns the nvme command status if a response was received (check enum nvme_status_field for the deets on what that status is actually saying).

Otherwise? It's -1, and errno gets set. Classic. Not the vibe you want, but at least she tells you what went wrong ✨

fr fr, if you get -1, go read errno before you start spiralling. it's giving "diagnostic" energy, use it. 😭
