qrtr_alloc_ctrl_packet(9)

💖 qrtr_alloc_ctrl_packet(9) 💖

okay so bestie, welcome to the Kernel API Manual page for qrtr_alloc_ctrl_packet — it's giving "tiny function, very important job" and honestly we're obsessed 🎀

---

✨ NAME ✨

qrtr_alloc_ctrl_packet — allocate a control packet skb, that's the whole vibe 💅

---

🦋 SYNOPSIS 🦋

struct sk_buff * qrtr_alloc_ctrl_packet (struct qrtr_ctrl_pkt **pkt ,
gfp_t flags );

---

🌸 ARGUMENTS 🌸

• pkt — a reference to a qrtr_ctrl_pkt pointer, i.e. a pointer-to-a-pointer, yes we love a double-pointer moment 👑
• flags — the type of memory to allocate (the gfp_t gossip, basically) ✨

---

💜 DESCRIPTION 💜

So here's the tea: this bad boy returns a newly allocated sk_buff, or NULL on failure 😭 — like, no packet for you, sorry bestie.

What it actually does? It allocates a sk_buff that's large enough to carry a qrtr_ctrl_pkt, and on success it hands you back a reference to that control packet in pkt. so pkt comes back pointing at the good stuff 🫶 slay.

ngl, if it returns NULL, that's your failure signal — check it, don't just yolo ahead 💀
