💅 iwpm_validate_nlmsg_attr(9) — the Kernel API Manual, bestie edition ✨

Okay so this is a page straight out of the Kernel API Manual, and we're talking about iwpm_validate_nlmsg_attr — a little function with a big job: sniffing out NULL netlink attributes like the main character it is. 🕵️‍♀️✨

🌸 NAME 🌸

iwpm_validate_nlmsg_attr — Check for NULL netlink attributes. That's literally the whole vibe check. 🎀

🦋 SYNOPSIS 🦋

int iwpm_validate_nlmsg_attr (struct nlattr *nltb[] , int nla_count );

Bestie, it takes two things and gives you back an int. That's it. That's the whole signature. 🫶

⭐ ARGUMENTS ⭐

  • nltb — Holds address of each netlink message attributes. It's the little array of pointers, one per attribute, and it's literally holding addresses like it's handing out invites. 💌
  • nla_count — Number of netlink message attributes. Just the count. How many we're checking. Not more, not less. 👑

💖 DESCRIPTION 💖

Returns error if any of the nla_count attributes is NULL.

That's it. That's the whole thing. It goes through all nla_count of your attributes and if even one of them is NULL, boom — error. No cap. 💀

So yes, this is the friend in the group chat who checks that literally everyone showed up. If somebody's missing, she will absolutely tell you. 😭
