💅 batadv_mcast_flags_dump_entry(9) — the Kernel API Manual page your group chat needed

okay so bestie, welcome to the Kernel API Manual, specifically the page for batadv_mcast_flags_dump_entry. yes that's a mouthful, no you're not gonna say it out loud. it's a batman-adv multicast flags thing and it's lowkey iconic. let's go 🦋

---

✨ NAME ✨

batadv_mcast_flags_dump_entry — dumps one entry of the multicast flags table out to a netlink socket. one entry. that's the whole gig. slay 💅

---

🌸 SYNOPSIS 🌸

int batadv_mcast_flags_dump_entry (struct sk_buff *msg , u32 portid ,
       struct netlink_callback *cb , struct batadv_orig_node *orig_node );

like, four arguments, returns an int. no cap, that's it. ✨

---

🎀 ARGUMENTS 🎀

okay so here's the vibe check on each param, bestie:

• msg — the buffer for the message. it's the lil container everything gets written into. 📦
• portid — the netlink port. that's where it's headed, iykyk. 🔌
• cb — the Control block containing additional options. yes capital-C Control block, that's how the manual says it, I don't make the rules. 🙈
• orig_node — the originator to dump the multicast flags of. this is like the main character of the operation, fr. 👑

---

💖 RETURN 💖

returns 0 or an error code. that's it. zero means we ate, error code means we did not eat. 😭

and the Kernel file it all lives in is ./net/batman-adv/multicast.c — that's the address, bestie, write it down. 🏠

---

heads up: the argument block spells it Control block with a capital C, so I'm keeping it exactly like that because the rule is facts don't change, only the vibe does. 💜

and that's the page!! tysm for reading, ily, go read some source 🫶
