batadv_dat_cache_dump_entry(9)

✨ NAME ✨

okay so welcome to the batadv_dat_cache_dump_entry(9) page in the Kernel API Manual! This function is literally doing one very specific job: dump one entry of the DAT cache table to a netlink socket. One entry. Netlink socket. No cap, that’s the whole assignment. 💅

🌸 SYNOPSIS 🌸

Here’s the exact signature, bestie — do not freestyle the types:

int batadv_dat_cache_dump_entry (struct sk_buff *msg , u32 portid ,
       struct netlink_callback *cb , struct batadv_dat_entry *dat_entry );

💅 ARGUMENTS 💅

• msg — the buffer for the message, aka where the message vibes live.
• portid — the netlink port. yes, that portid.
• cb — the control block containing additional options.
• dat_entry — the entry to dump. literally the chosen one.

🎀 RETURN 🎀

0 or an error code. That’s the whole mood: zero means good, error code means not the vibe.
