skb_queue_is_first(9)

🌸 skb_queue_is_first(9) — Kernel API Manual 🌸

okay so bestie, welcome to the skb_queue_is_first(9) page 💖 this one is from the Kernel API Manual, and it is literally a tiny yes/no vibe check for queue order. no cap, it's short, so we can absolutely slay it.

✨ NAME ✨

skb_queue_is_first — check if skb is the first entry in the queue. it's giving “am i first in line?” energy 🎀

🦋 SYNOPSIS 🦋

here's the signature, bestie — copy it exactly, we do not freestyle C signatures:

bool skb_queue_is_first (const struct sk_buff_head *list , const struct sk_buff *skb );

💅 ARGUMENTS 💅

• list — queue head. this is the head of the queue situation, the main character of the list.
• skb — buffer. this is the buffer you're checking on, the one asking if it's first.

🌈 DESCRIPTION 🌈

Returns true if skb is the first buffer on the list. that's the whole plot, bestie — no extra lore, no secret side quest. 💀
