batadv_send_tt_request(9)

💖 batadv_send_tt_request — the Kernel API Manual, bestie edition 🫶

Okay so this one is from the batadv_send_tt_request(9) manual page, and literally all it does is: send a TT Request message to a given node. That's it. That's the whole vibe. But let's get into it, because the details are everything ✨

---

🌸 NAME 🌸

batadv_send_tt_request — send a TT Request message to a given node

Like, you're the source of the message, you want translation table info from somebody, and this is the function that goes "hey bestie, send me your table" 💅

---

✨ SYNOPSIS ✨

bool batadv_send_tt_request (struct batadv_priv *bat_priv , struct
batadv_orig_node *dst_orig_node , u8 ttvn , struct
batadv_tvlv_tt_vlan_data *tt_vlan , u16 num_vlan , bool full_table );

Returns a bool, so like… true or false. Iconic of it, honestly.

---

🦋 ARGUMENTS 🦋

• bat_priv — the bat priv with all the mesh interface information. It's giving "main character struct," it knows everything about the mesh interface 🎀
• dst_orig_node — the destination of the message. Like, who you're sending this to. iykyk.
• ttvn — the version number that the source of the message is looking for. Obsessed with versioning, ngl.
• tt_vlan — pointer to the first tvlv VLAN object to request. First one only, periodt. 💅
• num_vlan — number of tvlv VLAN entries.
• full_table — ask for the entire translation table if true, while only for the last TT diff otherwise. So true = give me everything, false = just the recent diff. Choose wisely, bestie 👑

---

⭐ RETURN ⭐

true if the TT Request was sent, false otherwise.

That's it. No dramatic twist, no undefined behaviour horror story. Just a little boolean truth-telling 💀

💖 that's the whole page, bestie — go send some TT requests 💖

Cute little sign-off: this one lives in ./net/batman-adv, the manual's dated October 2026, and it's the batadv_send_tt_request(9) page from the Kernel API Manual set 💜🎀
