🌸 NAME 🌸

vmw_cmdbuf_res_lookup — literally just look up a command buffer resource. that's the whole thing. that's the assignment. 💅

---

✨ SYNOPSIS ✨

struct vmw_resource * vmw_cmdbuf_res_lookup (struct
vmw_cmdbuf_res_manager *man , enum vmw_cmdbuf_res_type res_type , u32
user_key );

so you hand it a manager, a resource type, and a user key, and it gives you back a struct vmw_resource *. the way that signature just sits there. gorgeous. 🫶

---

🦋 ARGUMENTS 🦋

• man — a pointer to the command buffer resource manager. like, the boss of the whole situation. 👑
• res_type — the resource type. this is the one that, when you combine it with the user key, identifies the resource. dynamic duo energy fr fr. 🔥
• user_key — the user key. that's it. that's the description. short and sweet, we respect it. 💜

---

🌈 DESCRIPTION 🌈

okay so here's the tea: on success, this returns a valid refcounted struct vmw_resource pointer. refcounted — meaning somebody's keeping tabs on it, don't you worry. 💅

on failure? it returns an error pointer. not NULL, not a vibe, an error pointer. so like, check that thing, bestie, don't just start dereferencing. 😭
