media_gobj_gen_id(9)

💅 media_gobj_gen_id(9)

Ok so bestie, welcome to the Kernel API Manual, section 9 — this is the kernel-internals corner of the docs, and today's main character is media_gobj_gen_id. She's small, she's specific, and she serves.

---

✨ NAME ✨

media_gobj_gen_id — encapsulates type and ID on at the object ID 🎀

(Yes, that's literally the description. "type and ID on at the object ID." The kernel docs said what they said and we respect the icon's choices. 💀)

---

🌸 SYNOPSIS 🌸

u32 media_gobj_gen_id (enum media_gobj_type type , u64 local_id );

Returns a u32. Takes two things. Vibes immaculate, signature tiny. 🫶

---

🦋 ARGUMENTS 🦋

• type — the object type, as defined at enum media_gobj_type. This is the "what kind of thing are we even talking about" of it all. ✨
• local_id — the next ID, pulled from struct media_device.id. This is the "which specific one" half of the duo. 🔥
