STRUCT VGETRANDOM_OPAQUE_PARAMS(9)

✨ NAME ✨

struct vgetrandom_opaque_params — the lil argument bundle you use when you're allocating memory for vgetrandom 🎀

This page lives in the Kernel API Manual, bestie, and it's literally all about that one struct. iykyk 💅

🦋 SYNOPSIS 🦋

struct vgetrandom_opaque_params {
    __u32 size_of_opaque_state;
    __u32 mmap_prot;
    __u32 mmap_flags;
    __u32 reserved[13];
 };

okay so that's the whole shape of it, no cap 👑

🌸 Members 🌸

• size_of_opaque_state — the size of each state that gets passed to vgetrandom. like, how much room each one needs 🫶
• mmap_prot — this is the value of the prot argument in mmap(2). yes, that mmap(2), the icon herself ✨
• mmap_flags — and this one's the value of the flags argument in mmap(2). matching set with mmap_prot, we love a coordinated moment 💖
• reserved — reserved for future use 👀 literally just sitting there being patient, main character energy of a placeholder fr fr

ngl bestie, reserved[13] is a whole vibe — thirteen __u32s of pure potential 💀

k that's the whole page 🧚 made with love in ./include/uapi/linux, version October 2026, and yeah the title still gets squished to struct vget...paque_params(9) in the corner — she's mysterious like that 💜
