STRUCT DRM_PVR_IOCTL_DEV_QUERY_ARGS(9)

✨ NAME ✨

struct drm_pvr_ioctl_dev_query_args — literally the args struct for %DRM_IOCTL_PVR_DEV_QUERY, bestie 💅

So this is a page out of the Kernel API Manual, and ngl it's a short one but it's important, so pay attention 🫶

---

🌸 SYNOPSIS 🌸

struct drm_pvr_ioctl_dev_query_args {
    __u32 type;
    __u32 size;
    __u64 pointer;
 };

okay so three fields, that's it, that's the whole vibe 🎀

---

🦋 Members 🦋

💜 type

Type of query and output struct. See enum drm_pvr_dev_query for the full menu, iykyk ✨

💜 size

Size of the receiving struct, see type 👀

And here's the slay part: after a successful call this gets updated to the written byte length 🔥 You can also use it to get the minimum byte length (peep pointer below). Why does that matter? Because it lets additional fields be appended to the structs in future — future-proofing, we love to see it 👑

💜 pointer

Pointer to struct type 💫

It must be large enough to contain size bytes, no cap. And if pointer is NULL, the expected size will just be returned in the size field and no other data gets written — so it's giving "just window shopping, not buying" 🙈
