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
       object was created with the flag TSS_HASH_OTHER, then the hash
       identifier has to be set by calling Tspi_SetAttribData to perform the
       sign operation.

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
