PVR USER OBJECTS.(9)

🎀 PVR user objects 🎀

(section 9, from the Kernel API Manual, bestie 💜)

💖 DESCRIPTION 💖

Okay so these are the macros that help you copy structured data and array data to and from userspace. Literally their whole job. ✨ Objects can differ in size, provided the minimum size allowed is specified — and you specify that using the last mandatory field in the struct. The way that works? Iconic. 🫶

All types used with the PVR_UOBJ_GET/SET macros must be listed here under PVR_UOBJ_MIN_SIZE, with the last mandatory struct field specified. No cap, that’s the rule. 🎀
