irdma_alloc_pd(9)

💅 irdma_alloc_pd(9) 💅

okay so you found yourself in the Kernel API Manual (yes, that's the manual name, we're fancy here ✨) and you clicked on irdma_alloc_pd. bestie, you're in the right place — grab a strawberry 🍓, this one's actually short and sweet.

---

🌸 NAME 🌸

irdma_alloc_pd — allocate protection domain

like, literally what it says on the tin. it allocates a protection domain. no cap.

---

✨ SYNOPSIS ✨

int irdma_alloc_pd (struct ib_pd *pd , struct ib_udata *udata );

(please do not come for me about the spacing, that's genuinely how it's written 💀 I keep the facts, I don't touch the characters)

---

🎀 ARGUMENTS 🎀

• pd — the PD pointer. your protection domain, your main character 👑 that's the thing you're allocating.
• udata — user data. yes, that's the whole description. short queen energy, we love a one-liner 🫶
