LIBNVMF_GET_OWNER_FROM_FCTX-LIBNVME3(2)

📦 version 3.2, in arch rolling

💅 NAME 💅

libnvmf_get_owner_from_fctx — okay so this one gets you the registry owner of a fabrics context ✨

No cap, that's the whole vibe. This page lives in the libnvme API manual, section 9, and it's here to hand you the owner of a fabrics context like it's passing you a note in class 🫶

🌸 SYNOPSIS 🌸

int libnvmf_get_owner_from_fctx (struct libnvme_global_ctx *ctx , struct
       libnvme_context *fctx , char **owner );

Three little args, and honestly? Iconic signature 💅

🎀 ARGUMENTS 🎀

  • ctx — the global context. Your main character. Everything hangs off this bestie ✨
  • fctx — the fabrics context describing the connection to check. Like, which connection are we snooping on 🔍
  • owner — the returned owner. Heads up bestie: this is NULL if there's no matching controller, or if the controller is unowned. So a NULL here is not a bug, it's a vibe 😭💀

🦋 DESCRIPTION 🦋

So this function is a convenience wrapper around libnvmf_get_owner_from_tid for callers who already have a libnvme_context instead of a bare TID. Literally a glow-up for your call site, ngl 🌈

Here's the tea on how it decides:

  • If fctx names an explicit device, its registry entry gets checked directly. Straight to the point, no detours, slay 🎯
  • Otherwise, a controller is resolved from fctx's connection parameters. Like, you didn't tell it which one, so it goes and figures it out 🧚

Either way, the owner contract is identical to libnvme_get_owner_from_tid. Same rules, same energy, no sneaky surprises — lowkey obsessed with that consistency 🫶

👑 RETURN 👑

  • 0 on success — but bestie, check owner, that's the whole point 💖
  • negative errno on failure. Not a vibe, but you know what to do with it 💀
fr fr do not forget to actually look at owner on that 0 return, okay? A success with an unread pointer is giving "read the docs bestie" 🙈

⭐ Sign-off ⭐

This cutie right here is from the libnvme API manual, dated October 2026 — libnvme girlies stay winning, and this page was brought to you by libnvme_get_owner_from_libnvme_get_owner_from_fctx(9) (yes, that's really how the footer reads, and honestly? she's messy but we love her 💜) 🎀 🦋 ✨
