Tspi_Hash_GetHashValue(3)  Library Functions Manual  Tspi_Hash_GetHashValue(3)

		   TCG Software	Stack Developer's Reference

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_Con-
       text_FreeMemory must be used to clean up	after this function, as	memory
       is allocated for	the prgbHashValue data.

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 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_GetHashValue conforms to the Trusted Computing	Group Software
       Specification version 1.1 Golden
