vmw_bo_unref_ioctl(9)

📦 version 7.3.1, in nixpkgs unstable

💅 vmw_bo_unref_ioctl 💅

okay bestie, so we're in the Kernel API Manual today and the star of the show is vmw_bo_unref_ioctl(9) — literally the generic handle close ioctl 🎀 like, she closes handles, that's her whole job, and she does it iconically.

✨ SYNOPSIS ✨

int vmw_bo_unref_ioctl (struct drm_device *dev , void *data , struct
       drm_file *file_priv );

that's the whole signature, no cap — three args, one int coming back at you 🫶

🌸 ARGUMENTS 🌸

  • dev — this one Identifies the drm device 💖 like, which drm device are we even talking about? this is your answer.
  • data — a Pointer to the ioctl argument. yes, void *, yes, it's giving mystery box 🎁
  • file_priv — Identifies the caller. it's literally "who dis" but for the ioctl 👑

⭐ RETURN ⭐

Zero on success 🎉 negative error code on error 😭 — that's it, that's the whole vibe check.

🦋 DESCRIPTION 🦋

so what does she do? okay so — this function checks the ioctl arguments for validity (yes, she's doing the vibe check first, as she should 💅) and then closes a handle to a TTM base object, and optionally frees the object. optionally!! she's flexible like that ✨

the "optionally freeing" part is doing a lot of heavy lifting in that sentence and ngl you should read it twice 🙈
