NAME
       Tspi_Hash_GetHashValue - get the current 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_GetHashValue(TSS_HHASH hHash, UINT32* pulHashValueLength, BYTE** prgbHashValue);

DESCRIPTION
       Tspi_Hash_GetHashValue  gets the hash value of a hash object. Tspi_Context_FreeMemory must
       be used to clean up after this function, as memory is allocated for the prgbHashValue  da-
       ta.

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

   pulHashValueLength
       Receives the length of the hash value data returned at the parameter prgbHashValue.

   prgbHashValue
       Receives a pointer to the hash value data.

RETURN CODES
       Tspi_Hash_GetHashValue returns TSS_SUCCESS on success, otherwise one of the following val-
       ues 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_GetHashValue conforms to the Trusted Computing Group Software Specification ver-
       sion 1.1 Golden
