batadv_vlan_id_valid(9)

💅 batadv_vlan_id_valid — yes bestie, this is a kernel API manual page

okay so real talk, this is batadv_vlan_id_valid from the Kernel API Manual, and honestly? it's a little guy with one job and it does it flawlessly. no cap.

---

✨ NAME ✨

batadv_vlan_id_valid — bestie, it literally just checks if the vlan id is in a valid batman-adv encoding 🦋

---

🌸 SYNOPSIS 🌸

bool batadv_vlan_id_valid (unsigned short vid );

that's it. that's the whole function signature. short, sweet, iconic 👑

---

🎀 ARGUMENTS 🎀

• vid — the VLAN identifier 💖 like, the actual vlan number you're asking about

---

⭐ RETURN ⭐

• true — comes back true when either no vlan is set or if the VLAN is in the correct range 🫶 slay
• false — everything else, sorry babe, that's a false 😭

so yeah: no vlan at all = valid, on the money range = valid, otherwise = nope. not me being a straightforward little boolean 💀
