  @special area   Profile Container Class
  @brief          This container class is used to handle the storage of
              profile data.
  @see            http://pwww/Tools/Autorisierung-Ergebnis981013.html


                Profile data has arbitrary length, but can
                be identified by a userid/SERVERDB combination.
                Each profile consists of length + bytestream.
                The profile data is only accessable via this interface.
                This is acting not on a ASCII-file....
                SERVERDB is used to identify a container file on per
                database base.

                  Using a token, which must be set to FIRST_TOKEN_EO28
                  to get the first profile, all profiles are returned
                  in order they are found by repeated calls to this function.
                  In such case reuse token.
                  Any delete or insert operation ('eo28_DelProfile' or
                  'eo28_SetProfile') during repeated calls to 'eo28_ScanProfiles'
                  will reset the token to FIRST_TOKEN_EO28.
                  If the last profile was found, the token will be set to 
                  LAST_TOKEN_EO28.
                  If no profile was found, the token will be set to 
                  NO_TOKEN_EO28.
                  To get only the username and profile length without the profile 
                  data, set pBuffer input parameter to NULL.
                  WARNING -- CHECKING THE RETURN CODE IS MANDATORY -- WARNING
                  In case of error (returning false) check length 
                  to make sure not only the buffer size was insufficient.
                  In such a case you can reuse token, but you will end up in
                  an endless loop if you do not check the return code...
