NAME
       Tspi_Hash_SetHashValue  - Sets the hash value of a hash object for non-
       SHA1 hash objects.

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_SetHashValue(TSS_HHASH hHash, UINT32 ulHashValueLength, BYTE* rgbHashValue);

DESCRIPTION
       Tspi_Hash_SetHashValue sets the hash value of a hash object. If the ob-
       ject was created with the flag TSS_HASH_OTHER, then the hash identifier
       has to be set by calling Tspi_SetAttribData to perform the sign	opera-
       tion.

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

   ulHashValueLength
       Indicates the length of the hash value data provided at	the  parameter
       rgbHashValue.

   rgbHashValue
       A pointer to the hash value data.

RETURN CODES
       Tspi_Hash_SetHashValue 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_SetHashValue conforms to the Trusted Computing Group Software
       Specification version 1.1 Golden
