tee_shm_get_va(9)

💅 tee_shm_get_va — a kernel API manual moment

okay bestie, welcome to the Kernel API Manual entry for tee_shm_get_va(9) — yes that (9) is the section number, we're in the deep kernel lore now 🧚✨

---

✨ NAME ✨

tee_shm_get_va — get the virtual address of a shared memory, plus an offset 🎀

---

🌸 SYNOPSIS 🌸

void * tee_shm_get_va (struct tee_shm *shm , size_t offs );

like, that's the whole vibe. two args, one pointer out. simple. iconic. 👑

---

🦋 ARGUMENTS 🦋

• shm — the shared memory handle 💖 (your main character struct, fr)
• offs — offset from the start of this shared memory. and here's the tea: it returns the virtual address of the shared memory + offs if offs is within the bounds of this shared memory, else an ERR_PTR 😭 so like… bounds check your girl, or you get an error pointer back. no cap.

ngl bestie, if you got here from a NULL-ish looking pointer, check offs against the size first — an ERR_PTR is not a real address, mwah 💋
