Further information
1. This function is used to enumerate fields of a record type. The second parameter is used to store the current location in the list of fields; if this parameter is
NULL, the first field of the record is returned. This function returns
NULL if it is called with the reference to the last field. Otherwise, the returned value can be used as the input parameter
