smb2_query_info(9)

💅 smb2_query_info — kernel API manual, but make it make sense

okay so bestie, welcome to the smb2_query_info(9) page ✨ this is a kernel API manual entry, and it's literally the handler for the smb2 query info command. that's the whole vibe. let's get into it 🫶

✨ NAME ✨

smb2_query_info — the handler for the smb2 query info command 🎀

🌸 SYNOPSIS 🌸

int smb2_query_info (struct ksmbd_work *work );

like, that's it. one function, one argument, returns an int. iconic minimalism 💅

🦋 ARGUMENTS 🦋

• work — the smb work that's holding the query info request buffer. it's giving "the whole package deal" — the request comes wrapped up in this bad boy 📦

⭐ RETURN ⭐

0 on success — and otherwise, an error. no cap, that's the entire contract 😌
