NAME

       PX_get_data_alpha — Get alpha data field

SYNOPSIS

       #include <paradox.h>

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

DESCRIPTION

       Converts a data field as it is stored in the database file into a string for the given encoding. You must
       set  the  target  encoding  before in order to recode the string. If you do not set the encoding the data
       will be returned as is. 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.

       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 field data starts with a null byte, -1 in case of an error and 1 otherwise.
