       encounred using tag.

       The freefare_strerror_r() functions does the same as freefare_strerror() but the error message is  copied
       into buffer for a maximum size of len chars.

       The  mifare_desfire_last_pcd_error()  function  returns the error code of the last function call from the
       library.

       The mifare_desfire_last_picc_error() function returns the error code returned by the last command run  on
