NE_MIN_MEM_REGION_SIZE(9)

🌸 NE_MIN_MEM_REGION_SIZE(9) — a Kernel API Manual moment 🌸

okay bestie, so this one lives in section 9 of the Kernel API Manual and honestly? it's a short one. a little snack. a single constant, but she's iconic and you need to know her 💅

✨ NAME ✨

NE_MIN_MEM_REGION_SIZE — the minimum size of a memory region, and that magic number is 2 MiB. literally. that's the whole vibe. no cap 🎀

🦋 SYNOPSIS 🦋

NE_MIN_MEM_REGION_SIZE

yep, that's it. she's a lone identifier, standing there looking cute 🫶

ngl bestie, this page is all about that 2 MiB floor — it's the smallest a memory region can be, so don't come in here trying to be smaller. periodt 💅

and that's the whole page! mwah 😘

this little love letter came from ./samples/nitro_enclaves, dated October 2026, and it's filed under NE_MIN_MEM_REGION_SIZE(9) — catch you in the man pages, bestie 🌈⭐💜
