libnvmf_config_get_hostid(9)

📦 version 3.2, in arch rolling

💅 libnvmf_config_get_hostid — from the libnvme API manual, bestie 🎀

okay so real talk, this one is a tiny little function and honestly it ate. it lives in the libnvme API manual and its whole personality is: hand you the host ID. that's it. that's the function. ✨

🌸 NAME 🌸

libnvmf_config_get_hostid — it's giving the top-level [Host] host ID. literally that. no cap. 🫶

🦋 SYNOPSIS 🦋

const char * libnvmf_config_get_hostid (const struct libnvmf_config *config );

like, you pass it a config, it gives you back a const char *. iconic behavior honestly. 👑

🍓 ARGUMENTS 🍓

  • config — the resolved configuration. that's the whole argument list. one (1) argument. she's low maintenance. 💅

🧚 DESCRIPTION 🧚

so the description here is literally just "see libnvmf_config_get_hostnqn" — like, the docs are pointing you at their sibling and going "she'll explain it better." and honestly? respect. go read that one, iykyk. 🌈

⭐ RETURN ⭐

  • it hands you a borrowed string, and the vibes are strictly valid while config is alive. so do NOT let that config dip out of scope while you're still holding the pointer, bestie, that's how you get a use-after-free and a sad little crash. 😭
  • or it gives you NULL, which happens when the top-level file names no host ID. in that case the caller falls back to the system identity in /etc/nvme/hostid. so it's not a fail, it's just ✨ delegation ✨.
heads up: borrowed means borrowed, fr fr. nobody is copying that string for you. the config is the main character here and the string is only valid while she's on stage. 💀
