libnvmf_params_get(9)

📦 version 3.2, in arch rolling

💅 libnvmf_params_get — the libnvme API manual, bestie edition

okay so real talk, this is a function from the libnvme API manual, and it's genuinely one of the most useful little gremlins in the whole connection-params situation. let's get into it 🫶

✨ NAME ✨

libnvmf_params_get — look up one connection parameter. that's it, that's the job. one param, one lookup, no drama 💖

🌸 SYNOPSIS 🌸

const char * libnvmf_params_get (const struct libnvmf_params *params ,
const char *key );

literally just hand it your params and a key and it hands you back a string. icon behavior ✨

🎀 ARGUMENTS 🎀

  • params — a resolved parameter set. like, the fully thought-out one, not a draft 🦋
  • key — the configuration key name. and by that we mean the "nvme connect" long-option name, e.g. "ctrl-loss-tmo". so yes, whatever you'd type as a long option to nvme connect, that's your key here. iykyk 💅

👑 RETURN 👑

so here's the vibe check on what comes back at you, and it's giving three different moods 😭

  • NULL — the key is unset. no value, nothing chosen, so the kernel default applies. it's not an error, it's just... default era 🌈
  • the empty string — that's an explicit reset to the kernel default. yes bestie, there is a difference between "never set" and "set to nothing on purpose" and this function will absolutely tell you which one you're in ⭐
  • the value string — otherwise! you got a real value, congrats, slay 🎉
⚠️ and the big one: the returned pointer is borrowed. not yours. do not free it, do not stash it in a global and go live your life, because it's only valid while the owning configuration is alive. the moment that config dips, your string is gone — periodt 💀
