✨ NAME ✨

netlbl_cipsov4_listall_cb — the cipso_v4_doi_walk() callback for LISTALL 🎀

🌸 SYNOPSIS 🌸

int netlbl_cipsov4_listall_cb (struct cipso_v4_doi *doi_def , void *arg
);

like, that's the whole signature, no cap 🫶

🦋 ARGUMENTS 🦋

• doi_def — the CIPSOv4 DOI definition 💖 this is the one being walked over, and she is the moment.
• arg — the netlbl_cipsov4_doiwalk_arg structure ⭐ it's the lil bundle of context getting passed along, iykyk.

🔥 DESCRIPTION 🔥

so this function is literally designed to be used as a callback to the cipso_v4_doi_walk function — like, that's her whole job, that's her purpose, that's her era ✨ and she's doing it specifically for use in generating a response for a LISTALL message 👑

on success she returns the size of the message 🌈 and on failure you get negative values back 😭 so yeah, check your return value, bestie, because a negative number means something went sideways fr fr.

heads up: negative return = failure. don't sleep on it 💀
