key_read(9)

💅 key_read(9) 💅

okay so this is key_read(9) from the Kernel API Manual, and she is lowkey iconic: she takes a key and transforms it into in-memory format. That's the whole vibe. No cap.

🎀 NAME 🎀

key_read — transform a key to in-memory format.

Like, literally the glow-up from stored key to in-memory key. Periodt.

✨ SYNOPSIS ✨

bestie, copy the signature exactly:

void key_read (const struct ubifs_info *c , const void *from , union
ubifs_key *to );

🌸 ARGUMENTS 🌸

• c — the UBIFS file-system description object. She's the context, the main character energy for the call.
• from — the key to transform. This is the input key, the one getting the makeover.
• to — the key to store the result. This is where the transformed key lands, no questions asked.
