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.
