nlmsg_for_each_attr_type(9)

💖 NAME 💖

okay bestie, welcome to the nlmsg_for_each_attr_type(9) page in the Kernel API Manual ✨ This one is literally here to iterate over a stream of attributes. That's the whole vibe: loop through attributes, keep your counter cute, and let the required type do its thing 💅

🦋 SYNOPSIS 🦋

nlmsg_for_each_attr_type (pos , type , nlh , hdrlen , rem );

No cap, that's the exact call shape — all five little arguments lined up and ready 🫶

🎀 ARGUMENTS 🎀

• pos — the loop counter, bestie; it gets set to the current attribute. Slay.
• type — the required attribute type for pos. It's the vibe check for which attribute you're on.
• nlh — netlink message header. Yes, the header of the message. Iconic.
• hdrlen — length of the family specific header. Keep it exact, okay?
• rem — initialized to len, and it holds bytes currently remaining in stream. That's the little countdown tracker, periodt.
