✨ ubifs_tnc_lookup(9) ✨

okay so bestie, this one lives in the Kernel API Manual and it's genuinely such a little icon. it's a lookup function, it's doing the most, and honestly? we love her for it. 🎀

🌸 NAME 🌸

ubifs_tnc_lookup — look up a file-system node. that's it, that's the whole vibe. she finds nodes. periodt. 💅

🦋 SYNOPSIS 🦋

int ubifs_tnc_lookup (struct ubifs_info *c , const union ubifs_key *key
, void *node );

like, copy it exactly bestie, don't freestyle the types, i'm begging 😭

✨ ARGUMENTS ✨

  • c — the UBIFS file-system description object. your main character struct, essentially. 👑
  • key — the node key to look up. this is the thing you're hunting for, iykyk. 🔍
  • node — and the node gets returned here. like, this is where she lands. 🫶

💖 DESCRIPTION 💖

so this function literally looks up and reads the node with key key. that's the whole arc. no cap.

⚠️ important bestie moment: the caller has to make sure the node buffer is large enough to fit the node. that's on you, not on her. she's not doing a vibe check on your buffer size, so pls don't set her up to fail 🙈

and the returns, because we always check the returns:

  • returns zero in case of success (slay 💅)
  • returns -ENOENT if the node was not found (she's just not there, it's giving ghosted 💀)
  • and a negative error code in case of failure (something went wrong, and we're being dramatic about it 😭)
