NAME
       Tspi_Hash_UpdateHashValue - update the hash value of a hash object

SYNOPSIS
       #include <tss/platform.h>
       #include <tss/tcpa_defines.h>
       #include <tss/tcpa_typedef.h>
       #include <tss/tcpa_struct.h>
       #include <tss/tss_typedef.h>
       #include <tss/tss_structs.h>
       #include <tss/tspi.h>

       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_OTH-
       ER, then this method will return an error. 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.


       TSS_E_BAD_PARAMETER
              One or more parameters is bad.


       TSS_E_HASH_INVALID_LENGTH
              Hash length is inconsistent with hash algorithm.


       TSS_E_HASH_NO_DATA
              Hash object has no internal hash value.



CONFORMING TO
       Tspi_Hash_UpdateHashValue conforms to the Trusted Computing Group Soft-
       ware Specification version 1.1 Golden
