rdma_copy_ah_attr(9)

okay bestie, welcome to the rdma_copy_ah_attr(9) page from the Kernel API Manual — short, sweet, and very “copy that, bestie.” 🫶

✨ NAME ✨

rdma_copy_ah_attr — Copy rdma ah attribute from source to destination. That’s the whole gig: source in, destination out, no cap. 💅

🌸 SYNOPSIS 🌸

void rdma_copy_ah_attr (struct rdma_ah_attr *dest , const struct
rdma_ah_attr *src );

🎀 ARGUMENTS 🎀

• dest — Pointer to destination ah_attr. The contents of the destination pointer are assumed to be invalid, and the attributes are overwritten. So don’t get attached to whatever was chillin’ there before, bestie — it’s getting replaced. 💀
• src — Pointer to source ah_attr. This is the one you’re copying from, the main character of the operation. 👑

⚠️ Heads up: dest is assumed to point at invalid contents, and the attributes are overwritten. That’s not a vibe check you can skip. 🙈
