STRUCT VMMDEV_HOST_VERSION(9)

💖 struct vmmdev_host_version(9) 💖

okay so bestie, welcome to the Kernel API Manual page for struct vmmdev_host_version — yes it's a whole little struct with main character energy, and yes we're gonna go through every single field together 🫶

---

🌸 NAME 🌸

struct vmmdev_host_version — literally the VirtualBox host version request structure. that's her whole job 💅

---

✨ SYNOPSIS ✨

struct vmmdev_host_version {
    struct vmmdev_request_header header;
    u16 major;

🎀 Members 🎀

so the source doesn't give us cute one-line blurbs for each field (rude, honestly 🙈), but here's everybody living in this struct, in order:

• struct vmmdev_request_header header — the request header, first in line, always.
• u16 major — the major field, she's a u16.
• u16 minor — the minor field, also a u16.
• u32 build — the build field, she's a u32.
• u32 revision — the revision field, u32 too.
• u32 features — the features field, u32, slaying at the end of the struct ✨

🦋 Description 🦋

okay so the actual tea: VBG uses this to detect the presence of new features in the interface. that's it, that's the vibe — she's the little version-check queen that tells you what new stuff the interface can do 👑
