frame_vector_create(9)

💖 frame_vector_create(9) 💖

okay bestie, so this one lives in the Kernel API Manual and it's literally the "reserve me a lil parking garage for pinned pfns" function. let's get into it 🫶

---

✨ NAME ✨

frame_vector_create — allocate & initialize structure for pinned pfns 🎀

like, it builds the whole thing from scratch and hands it back ready to go. no cap.

---

🌸 SYNOPSIS 🌸

struct frame_vector * frame_vector_create (unsigned int nr_frames );

---

🦋 ARGUMENTS 🦋

• nr_frames — number of pfns slots we should reserve 💅 this is you telling the function how many spots to set aside. pick a number, any number (but like, a sensible one).

---

⭐ DESCRIPTION ⭐

so what it does is: allocate and initialize struct pinned_pfns so it's able to hold nr_pfns pfns. that's the whole vibe. it's giving setup energy — you give it a count, it gives you back a structure all allocated and initialized and ready for pfns to move in. 🔥

no surprises, no drama, just a fresh structure with room to breathe. periodt.
