💅 drm_property_create_range (9) — Kernel API Manual, bestie edition ✨

okay so picture this: you're deep in drm_property_create_range(9), the Kernel API Manual, and you just want a property that takes a nice unsigned number between two values. that's it. that's the whole vibe. let's go 🎀

🌸 NAME 🌸

drm_property_create_range — create a new unsigned ranged property type. yes, unsigned, bestie, don't come at me with your negative numbers, there's a different function for that 👀

✨ SYNOPSIS ✨

struct drm_property * drm_property_create_range (struct drm_device *dev
, u32 flags , const char *name , uint64_t min , uint64_t max );

not me formatting this exact signature so it stays character-for-character, because i respect the source 💅

🦋 ARGUMENTS 🦋

  • dev — the drm device. the main character. everything happens because of her 🫶
  • flags — flags specifying the property type. the little settings gremlins that decide what kind of property she's gonna be ✨
  • name — name of the property. her government name, if you will 👑
  • min — minimum value of the property. the floor. the bare minimum. we've all been there 😭
  • max — maximum value of the property. the ceiling. she's booked and busy and this is her limit 🔥

💖 DESCRIPTION 💖

so this creates a new generic drm property, which you can then attach to a drm object with drm_object_attach_property. it's giving "build her, then find her a home" energy 🏠✨

the returned property object must be freed with drm_property_destroy — and ngl the good news is that's done automatically when you call drm_mode_config_cleanup. so like, cleanup is lowkey handled for you, but you still gotta know it exists, iykyk 🧹💜

and here's the actual contract, no cap: userspace is allowed to set any unsigned integer value in the (min, max) range, inclusive. inclusive, bestie. both ends. she's generous like that 🌈

⭐ RETURN ⭐

  • A pointer to the newly created property on success 🎉
  • NULL on failure 💀

that's it. that's the whole return section. short and iconic. periodt 🎀

ok but seriously — she only does unsigned values, and both min and max count. if that's not your problem, check out the signed version up there in SEE ALSO, bestie 🙈
