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.
