netif_running(9)

🌸 netif_running(9) — the "is it up tho" check 🌸

okay so real quick, this page lives in the Kernel API Manual and it's about netif_running — yeah that's the whole vibe. let's get into it bestie 💅

---

✨ NAME ✨

netif_running — test if up. that's it. that's the function. it tests. if up. iconic behavior honestly 🎀

---

🦋 SYNOPSIS 🦋

bool netif_running (const struct net_device *dev );

yes she returns a bool and yes she takes one const struct net_device * — no surprises, no drama, we love a low-maintenance signature 🫶

---

💖 ARGUMENTS 💖

• dev — the network device. that's the one you're asking about. literally just pass her the device and she'll tell you what's up (or whether it's up, iykyk) ✨

---

🔥 DESCRIPTION 🔥

so what does it actually do? she tests if the device has been brought up. that's the whole thing. no cap, no hidden side quests, no "oh also it does this other thing" — nope. you hand her a device, she tells you if it's been brought up. vibe check complete 💀

ngl this one is short and sweet, but that's the point — the description says exactly one (1) thing and we're not inventing extra lore for it 🙈
