tnc_read_hashed_node(9)

🌸 NAME 🌸

okay so bestie, welcome to the Kernel API Manual page for tnc_read_hashed_node(9) ✨. The name line is giving: tnc_read_hashed_node — read a "hashed" leaf node. periodt 💅.

🎀 SYNOPSIS 🎀

int tnc_read_hashed_node (struct ubifs_info *c , struct ubifs_zbranch *zbr , void *node );

💖 ARGUMENTS 💖

• c — UBIFS file-system description object. iconic.
• zbr — key and position of the node.
• node — node is returned here. yes, it comes back through this one 🫶.

🦋 DESCRIPTION 🦋

okay so this function reads a "hashed" node defined by zbr — and the way it does that is from the leaf node cache (if it is there) or from the hash media, in which case the node is also added to LNC ✨.

Returns zero in case of success or a negative error code in case of failure. no cap, that's the whole vibe check 💅.
