📦 version 3.2, in arch rolling

💖 libnvme_alloc_huge(9) 💖

okay bestie, welcome to the libnvme API manual ✨ this lil page is literally all about libnvme_alloc_huge and ngl it's a whole vibe. sit down, grab a strawberry 🍓, let's get into it.

🌸 NAME 🌸

libnvme_alloc_huge — allocate a huge page-backed memory buffer 👑

like, it gets you a memory buffer that's backed by huge pages. fancy. no cap. 💅

✨ SYNOPSIS ✨

void * libnvme_alloc_huge (size_t len , struct libnvme_mem_huge *mh );

that's the whole signature, copy it exactly bestie, don't be out here renaming stuff 🙈

🎀 ARGUMENTS 🎀

  • len — the size of the memory buffer, in bytes 📏 (yes, bytes, the classic unit)
  • mh — the huge memory allocation descriptor 🗂️ this is where the deets get parked

🦋 DESCRIPTION 🦋

so the way that this works is: it attempts to allocate a memory buffer backed by huge pages. attempts!! it's giving "we'll try our best" energy 😭

the allocation details get stored in mh, and — listen to me, this part matters — you must release it later using libnvme_free_huge. don't just leave it lying around, bestie, that's not the move. 🚨

🌈 RETURN 🌈

  • success → a pointer to the allocated memory buffer 🫶 slay
  • failure → NULL 💀 that's it, that's the whole deal
lowkey reminder: mh holds the allocation details, so hold onto it and hand it over to libnvme_free_huge when you're done. periodt. ✨

and that's the page, bestie!! 🧚 this iconic lil doc came to you courtesy of the libnvme API manual, libnvme_alloc_huge, dated October 2026 ⭐ go forth and allocate responsibly, mwah 💜🎀
