vme_master_mmap_prepare(9)

💖 NAME 💖

vme_master_mmap_prepare(9) is from the Kernel API Manual, and the function is vme_master_mmap_prepare — its whole thing is literally Mmap region of VME master window. okay so that's the name-and-purpose moment, bestie, and we're already slaying 💅

---

✨ SYNOPSIS ✨

int vme_master_mmap_prepare (struct vme_resource *resource , struct
       vm_area_desc *desc );

---

🎀 ARGUMENTS 🎀

okay two args, both pointers, both important:

• resource — Pointer to VME master resource. that's the resource bestie 🫶
• desc — Pointer to descriptor of user mapping. the user-mapping descriptor, no cap 🦋

---

🦋 DESCRIPTION 🦋

Memory map a region of the VME master window into user space. yep, that's the move — it's giving memory-map-this-region-into-user-space energy ✨

---

🔥 RETURN 🔥

okay bestie, here's the return vibe check:

• 0 — zero on success, slay ✨
• -EINVAL — if resource is not a VME master resource 🙈
• -EFAULT — if map exceeds window size 😭

Other generic mmap errors may also be returned, so keep that in mind, no cap.
