vmw_user_stream_lookup(9)

🎀 NAME 🎀

Okay bestie, this is vmw_user_stream_lookup(9) from the Kernel API Manual, and its whole personality is: look up a struct vmw_user_stream from a handle. That's the name, that's the mission, slay 💅.

✨ SYNOPSIS ✨

int vmw_user_stream_lookup (struct vmw_private *dev_priv , struct ttm_object_file *tfile , uint32_t *inout_id , struct vmw_resource **out );

Here's the signature in all its iconic glory ✨.

🎀 ARGUMENTS 🎀

• dev_priv — Pointer to a struct vmw_private. That's it, that's the pointer 🫶.
• tfile — The struct ttm_object_file identifying the caller. It's literally the caller's little ID situation 💳.
• inout_id — In: The user-space handle. Out: The stream id. Yes, it does both — main character energy 🔄.
• out — On output contains a refcounted pointer to the embedded struct vmw_resource. Refcounted, bestie, don't forget that part 💅.

🦋 RETURN 🦋

0 if successful. Negative error value on failure. No cap, that's the whole return sitch 😭.
