NAME

       PX_get_data_double — Get double data field

SYNOPSIS

       #include <paradox.h>

       int  PX_get_data_double(pxdoc_t  *pxdoc,  char  *data,  int len, double
       *value)

DESCRIPTION

       Converts a data field as it stored in the database file into  a  double
       for  the  host  architecture.  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.

RETURN VALUE

       Returns 0 if the value is NULL, -1 in case of an error and 1 otherwise.
