💖 nvme_get_log_dispersed_ns_participating_nss(2) 💖

okay bestie, welcome to the libnvme API manual ✨ pull up a chair, we're reading a man page and it's actually gonna slap

---

🎀 NAME 🎀

nvme_get_log_dispersed_ns_participating_nss — the function that goes and retrieves the Dispersed Namespace Participating NVM Subsystems Log. yes that's the whole name. yes it's a mouthful. no we are not shortening it, it's iconic 👑

---

✨ SYNOPSIS ✨

int nvme_get_log_dispersed_ns_participating_nss (int fd , __u32 nsid ,
       __u32 len , struct nvme_dispersed_ns_participating_nss_log *log );

four arguments, one int coming back at you. simple. clean. we love to see it 🫶

---

🌸 ARGUMENTS 🌸

• fd — the file descriptor of your nvme device. it's literally the doorway to the hardware, so like, don't hand it a random number and hope for the best 🙈
• nsid — the Namespace Identifier. which namespace are we talking about, bestie? this is how you tell it 🦋
• len — the allocated length of the log page. how much room did you set aside for the log page? that number. exactly that number 💅
• log — the user address where the log page gets stored. you're handing it a place to put the goods, so make sure that pointer points somewhere real ⭐

---

🔥 RETURN 🔥

so here's what comes back at you:

• if a response was actually received, you get the nvme command status (peep enum nvme_status_field for what those values mean, iykyk)
• otherwise you get -1 and errno gets set

not me getting -1 and forgetting to check errno... 😭 bestie. check errno. it's right there. it's telling you what went wrong.

and that's the whole page, no notes, no skips, every single detail preserved because that's just how we do it around here 💜
