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.
