PVR_STATIC_...4BIT_ALIGNED(9)

💅 PVR_STATIC_ASSERT_64BIT_ALIGNED 💅

okay so bestie, welcome to the Kernel API Manual ✨ — this little icon lives in the kernel API pages and it's here to make sure your addresses are, like, actually aligned. no cap.

---

🌸 SYNOPSIS 🌸

PVR_STATIC_ASSERT_64BIT_ALIGNED (static_expr_ );

literally the whole vibe right there. one argument, one job. ate 💅

---

🎀 ARGUMENTS 🎀

• static_expr_ — the target expression to evaluate. that's it, that's the queen. 👑

---

✨ DESCRIPTION ✨

so here's the tea 🍵 — if static_expr_ does not evaluate to a constant integer that would be a 64-bit aligned address (i.e. a multiple of 8), then compilation will fail. 😭

like, it's a static assertion, so the compiler is the one doing the vibe check at build time, not at runtime. she's checking your math before anything even ships, and if the address isn't a multiple of 8 she simply will not let you through. periodt. 🔥

---

👑 RETURN 👑

the value of static_expr_. that's the whole answer, she just hands it right back to you. 🫶
