libnvmf_read_hostnqn(9)

πŸ“¦ version 3.2, in arch rolling

πŸ’– libnvmf_read_hostnqn β€” get the configured host nvm qualified name πŸ’–

okay so bestie, this one lives in the libnvme API manual and it's literally just about fetching your host NQN. short page, but we're gonna give it the attention it deserves. ✨


🌸 SYNOPSIS 🌸

char * libnvmf_read_hostnqn (struct libnvme_global_ctx *ctx );

like, one function, one arg, returns a char *. clean. no notes. πŸ’…


πŸŽ€ ARGUMENTS πŸŽ€

  • ctx β€” a struct libnvme_global_ctx object. that's your context bestie, it's where the default might already be chillin'.

πŸ¦‹ DESCRIPTION πŸ¦‹

so here's the vibe check πŸ‘‘: this returns ctx's hostnqn default if one is set. that's it, that's the first move. but if there's no default set? it goes and reads the name from $SYSCONFDIR/nvme/hostnqn instead. and btw $SYSCONFDIR is usually /etc β€” just so you know where you're poking around. 🫢

πŸ™ˆ lowkey important caveat: an empty ctx default suppresses the file lookup. so like, empty string β‰  "go check the file", it means "nope, don't even bother looking". don't get caught out by that one fr fr.

and listen β€” this is not the identity that a connect actually uses. i know, i know, shocking 😭. if you want the full resolution order, go see libnvmf_host_get_ids. that's the main character for that particular job, this one's more of a supporting role. πŸ’€


⭐ RETURN ⭐

  • returns the host nqn as a char * πŸ’–
  • or NULL if it wasn't successful πŸ˜”
  • if it does find one, you, the caller, are responsible for freeing the string. yes you. don't forget. no cap. πŸ”₯
