string privs_file( string filename );
The privs_file() function is called in the master object when a new file is created. The `filename' of the object is passed as the argument, and the string that privs_file() returns is used as the new object's privs string.
The privs_file() functionality is only available if the driver is compiled with the PRIVS option defined.
