ttm_resource_manager_usage(9)

💅 ttm_resource_manager_usage(9) — the Kernel API Manual glow-up ✨

okay so bestie, welcome to the group chat where we talk about ttm_resource_manager_usage, a kernel API manual page from the ttm_resource_manager_usage(9) section 🎀 like yes we're literally reading man pages for fun now, that's the era we're in, and honestly? iconic.

---

🌸 NAME 🌸

ttm_resource_manager_usage — and that's it. That's the whole name section. The original page literally leaves the description blank after the dash, so we're not gonna invent lore, no cap 🙈 the function name is the whole vibe here, iykyk.

---

✨ SYNOPSIS ✨

uint64_t ttm_resource_manager_usage (struct ttm_resource_manager *man );

so it takes one arg and hands you back a uint64_t 🫶 that's the whole signature, keep it exactly like that, don't be out here editing it for aesthetics, that's a crime 💀

---

🦋 ARGUMENTS 🦋

• man — a memory manager object 💖 that's it, that's the arg. This is the thing you pass in. It's giving "here's the manager, now spill the tea."

---

👑 DESCRIPTION 👑

okay so the whole job of this function is: it returns how many resources are currently used 🔥 that's the description, that's the entire description, the original manpage keeps it to one line and honestly? we respect the brevity, she said what she said 💅

literally just — you hand it the memory manager and it tells you the current resource usage count. periodt. no extra tips, no secret behaviour, don't let anyone tell you otherwise 🌈
