NAME

       PX_get_data_bcd — Get bcd data field

SYNOPSIS

       #include <paradox.h>

       int PX_get_data_bcd(pxdoc_t *pxdoc, char *data, int len, char **value)

DESCRIPTION

       Converts  a data field as it stored in the database file into a bcd string. The string will not be longer
       than 20 chars including the final 0. It contains only the characters  `+',  `-',  `0-9',  and  `.'.   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. len is the number  of
       digits after the decimal point.

       The  function  allocates  memory  for  the  string returned in *value. This memory has to be freed by the
       application.

              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.
