smb2_write(9)

💖 NAME 💖

Okay bestie, welcome to the Kernel API Manual — this one is smb2_write, and it’s literally the handler for smb2 write from file. Kernel business, but make it cute ✨

🦋 SYNOPSIS 🦋

int smb2_write (struct ksmbd_work *work );

🌸 ARGUMENTS 🌸

• work — the smb work containing the write command buffer. That’s the whole argument, and it’s lowkey carrying the request 🫶

🎀 RETURN 🎀

• 0 on success, otherwise error. Slay if it’s 0; if it’s an error, we’re coping 😭
