ubifs_pnode_lookup(9)

💅 NAME 💅

Bestie, this is ubifs_pnode_lookup — lookup a pnode in the LPT. 💅 (Kernel API Manual girlies, this is your page, and yes, we're keeping it cute.)

✨ SYNOPSIS ✨

Okay so the signature is literally:

struct ubifs_pnode * ubifs_pnode_lookup (struct ubifs_info *c , int i );

🎀 ARGUMENTS 🎀

• c — UBIFS file-system description object. That's the main-character context, fr fr.
• i — pnode number (0 to (main_lebs - 1) / UBIFS_LPT_FANOUT). Respect the range, bestie.

🦋 DESCRIPTION 🦋

The plot is simple and iconic: on success this function returns a pointer to the pnode; on failure it returns a negative error code. No cap, that's the whole contract. 🫶
