OK, my 2 Pfennings worth ...
The calls that open files for writing and that write them simply return an
error code if things fail. It would be up to the client to implement some
sort of exit that tells you that it was quota exceeded, but I don't think
there is any special code for that.
I think the easiest is goint to be the original suggestion, have something
defined in the smb.conf that specifies a script or some action when quota
is exceeded, and then send a popup message to the client with the error.
