pvr_dev_quer...ime_info_get(9)

💅 pvr_dev_quer...ime_info_get(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ this one is literally pvr_dev_quer...ime_info_get(9) — yes the name is truncated with the ... and no we are not fixing it, that's just how it's printed, iykyk 🫶

---

🌸 NAME 🌸

pvr_dev_query_runtime_info_get —

and that's it. that's the whole name section. no description, no little dash-explainer, nothing. it's giving mysterious main character energy 💀 (we love a function that lets its actions speak fr fr)

---

✨ SYNOPSIS ✨

int pvr_dev_query_runtime_info_get (struct pvr_device *pvr_dev , struct
drm_pvr_ioctl_dev_query_args *args );

look at her go 😭 two structs and an int, clean, iconic, no notes 💅

---

🎀 ARGUMENTS 🎀

• pvr_dev — the device pointer. that's your lil handle on the actual device, bestie 🖥️
• args — [IN] the device query arguments, and inside them there's a pointer to a userspace struct drm_pvr_dev_query_runtime_info. so yes, it's an args-struct holding a pointer to another struct. struct-ception, we're obsessed 🌀✨

---

🦋 DESCRIPTION 🦋

so here's the vibe check 👑: if the query object pointer is NULL, then the size field gets updated with the expected size of the query object. that's it. that's the whole description. short and slay 💖

tl;dr — hand it a NULL pointer and it'll tell you how big your buffer needs to be. very demure, very considerate 🌸

---

🔥 RETURN 🔥

• 0 on success — or if size is requested using a NULL pointer (yes, asking for the size counts as a win too, we stan 🫶), or
• -E2BIG if the indicated length of the allocation is less than is required to contain the copied data — i.e. your buffer is too smol, bestie, and it is NOT gonna squeeze in there 😭, or
• -EFAULT if local memory could not be copied to userspace — the copy did not go through, no cap 💀
