drm_property_create_blob(9)

✨ drm_property_create_blob(9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 — this little cutie lives in the drm_property_create_blob(9) corner of the universe and it's literally here to make you a brand-new blob property. let's get into it 🎀

---

🌸 NAME 🌸

drm_property_create_blob — create new blob property 🫶

---

🦋 SYNOPSIS 🦋

struct drm_property_blob * drm_property_create_blob (struct drm_device
*dev , size_t length , const void *data );

---

💖 ARGUMENTS 💖

• dev — the DRM device you're creating this property for, like, obviously 🧚
• length — how much space to allocate for the blob data, no cap
• data — if you actually pass this in, it copies data into the blob 📋

---

👑 DESCRIPTION 👑

so what it does is: it creates a new blob property for a specified DRM device, and optionally copies data in for you. easy!

⚠️ but listen — blob properties are meant to be invariant, which is a fancy way of saying once it's set, it's set. so the data must be filled out before the blob is used as the value of any property. don't come back later trying to change it, bestie, it's not that kind of blob 💀

---

⭐ RETURN ⭐

on success you get a new blob property with a single reference 🔥

on failure you get an ERR_PTR value 😭 (check for it, please, i'm begging)
