                                                                                            PX_GET_DATA_BYTES(3)

       Reads  a  data field consisting of an array of bytes into a chunk of memory and returns the pointer to it
       in value. The memory is allocated by this function and must be freed  by  the  calling  application.  You
       should use this function instead of accessing the data directly.

       data  points  to the start of the data field in the record. It must be calculated by summing up all field
       length before the field to operate on and add it to the base pointer of the record.

              Note:

              This function is deprecated and obsolete if PX_retrieve_record(3) is used.
