write_tag_3_packet(9)

🎀 NAME 🎀

Hey bestie, welcome to the write_tag_3_packet(9) page from the Kernel API Manual ✨. The original one-liner after the dash is literally blank, so I'm not gonna invent a summary — the name is the whole flex here 💅.

✨ SYNOPSIS ✨

int write_tag_3_packet (char *dest , size_t *remaining_bytes , struct
       ecryptfs_auth_tok *auth_tok , struct ecryptfs_crypt_stat *crypt_stat ,
       struct ecryptfs_key_record *key_rec , size_t *packet_size );

🦋 ARGUMENTS 🦋

• dest — the buffer you're writing the packet into, periodt.
• remaining_bytes — the maximum number of bytes that can be written, aka your byte budget 🫶.
• auth_tok — authentication token.
• crypt_stat — the cryptographic context, no cap.
• key_rec — encrypted key 🔐.
• packet_size — this function will write the number of bytes that end up constituting the packet; it gets set to zero on error. Important detail, bestie 💖.

🔥 DESCRIPTION 🔥

Returns zero on success; non-zero on error. That's it — that's the whole description. The vibe check is binary: 0 = slay, non-zero = not slay 😭. No extra lore in the original, so no extra lore here.
