     TSS_RESULT Tspi_Hash_UpdateHashValue(TSS_HHASH hHash, UINT32 ulDataLength, BYTE* rgbData



DESCRIPTION
     Tspi_Hash_UpdateHashValue updates the hash value of  a  hash
     object  with new information. If the object was created with
     the flag TSS_HASH_OTHER, then this method will return an er-
     ror.     The     object     can't    be    modified    after
     Tspi_Hash_SetHashValue,              Tspi_Hash_GetHashValue,
     Tspi_Hash_Sign,   or   Tspi_Hash_VerifySignature  have  been
     called on it.


PARAMETERS
  hHash
     The handle to the hash  object  instance  whose  hash  value
     should be signed.

  ulDataLength
     Indicates the length of the data provided at  the  parameter
     rgbData.

  rgbData
     A pointer to the data.


RETURN CODES
     Tspi_Hash_UpdateHashValue returns  TSS_SUCCESS  on  success,
     otherwise one of the following values is returned:

     TSS_E_INVALID_HANDLE
          hHash is not a valid handle.


     TSS_E_INTERNAL_ERROR
          An internal SW error has been detected.
