privs_file - specifies the privs string to give to a newly created object
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.
