execmem_vmap(9)

🌸 NAME 🌸

Okay bestie, this is execmem_vmap(9) from the Kernel API Manual, and it’s here to create virtual mapping for EXECMEM_MODULE_DATA memory — no cap, that’s the whole name vibe 💅✨

---

✨ SYNOPSIS ✨

The signature is giving main-character energy:

struct vm_struct * execmem_vmap (size_t size );

---

🎀 ARGUMENTS 🎀

• size — the size of the virtual mapping, in bytes. That’s the whole argument, bestie — it’s a size_t, and it’s doing exactly what it says on the label 🫶

---

💖 DESCRIPTION 💖

So basically, this maps a virtually contiguous area in the range suitable for EXECMEM_MODULE_DATA. That’s the entire description and honestly it ate 🔥

Virtually contiguous, suitable for EXECMEM_MODULE_DATA — those details are important, keep them close 🧚

---

🦋 RETURN 🦋

You get the area descriptor on success, or NULL on failure. That’s it — success = area descriptor, failure = NULL, periodt 💀✨
