make_idx_node(9)

💖 NAME 💖

make_idx_node — make an index node for fill-the-gaps method of TNC commit. periodt ✨

okay so you're looking at make_idx_node(9) from the Kernel API Manual, and it's giving “tiny but crucial UBIFS TNC commit helper” energy. let's get into it, bestie 💅

✨ SYNOPSIS ✨

the whole signature, no cap:

int make_idx_node (struct ubifs_info *c , struct ubifs_idx_node *idx ,
       struct ubifs_znode *znode , int lnum , int offs , int len );

🌸 ARGUMENTS 🌸

here's the cast of parameters, and yes every single one matters 🫶

• c — the UBIFS file-system description object. iconic context behavior.
• idx — the buffer in which to place the new index node. that's where the new node goes 💖
• znode — the znode from which to make the new index node. source material, fr fr.
• lnum — the LEB number where the new index node will be written. remember this number, bestie 🔥
• offs — the offset where the new index node will be written. location location location ✨
• len — the length of the new index node. gotta know the size 👑
