samba - Aug 2016 - Is it possible to send a message to samba client from samba vfs module?

For some reason, I want to write a VFS module to prevent user from deleting
certain folder or files. I want to do it in a user-friendly way. For
example, the client pops up a dialog, saying something on why he/she cannot
fulfill the operation. If not all client works, I hope at least the Windows
File Explorer will do.

Is it possible?

Not really. There's no way for a server to asynchronously notify
a client with specific text when an operation fails.

Couldn't you do something like the "net send" command?
