nla_get_s16_default(9)

💖 NAME 💖

okay so bestie, this is nla_get_s16_default — a little kernel helper from the Kernel API Manual, section 9, and its whole entire job is: return the payload of an s16 attribute, or the default. that's it. that's the vibe. 🎀

---

✨ SYNOPSIS ✨

s16 nla_get_s16_default (const struct nlattr *nla , s16 defvalue );

like… it takes a thing and a fallback and gives you a number back. slay. 💅

---

🫶 ARGUMENTS 🫶

• nla — an s16 netlink attribute, and here's the icon ✨ twist: it may be NULL. yes fr, NULL is allowed here, she's built different.
• defvalue — the default value to use if nla is NULL. your safety net. your emotional support number. 💖

---

🌸 RETURN 🌸

it gives you back the value of the attribute, or the default value if not present. bestie-proof: if the attribute is there you get the attribute's value, and if it's not, you get defvalue. no cap, that's the whole contract. 🔥
