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_OTHER,  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	Software
     Specification version 1.1 Golden

SEE ALSO
