NAME
       Tspi_PcrComposite_GetPcrValue  -  get  the  digest value of a given PCR index inside a PCR
       composite object.

SYNOPSIS
       #include <tss/platform.h>
       #include <tss/tcpa_defines.h>
       #include <tss/tcpa_typedef.h>
       #include <tss/tcpa_struct.h>

       #include <tss/tspi.h>

       TSS_RESULT Tspi_PcrComposite_GetPcrValue(TSS_HPCRS hPcrComposite,    UINT32 ulPcrIndex,
						UINT32*   ulPcrValueLength, BYTE** rgbPcrValue);

DESCRIPTION
       Tspi_PcrComposite_GetPcrValue returns the digest value of a given PCR index inside  a  PCR
       composite object.

PARAMETERS
   hPcrComposite
       Handle of the PCR composite object instance where a PCR value should be returned.

   ulPcrIndex
       This parameter indicates the index of the PCR to read.

   ulPcrValueLength
       The length (in bytes) of the rgbPcrValue parameter.

   rgbPcrValue
       After successful completion this parameter recieves a pointer to the memory block contain-
       ing the PCR value of the PCR indicated by ulPcrIndex.

RETURN CODES
       Tspi_PcrComposite_GetPcrValue returns TSS_SUCCESS on success, otherwise one of the follow-
       ing values are returned:

       TSS_E_INVALID_HANDLE - Either hPcrComposite or ulPcrIndex is an invalid parameter.

       TSS_E_INTERNAL_ERROR - An error occurred internal to the TSS.

CONFORMING TO
       Tspi_PcrComposite_GetPcrValue  conforms to the Trusted Computing Group Software Specifica-
       tion version 1.1 Golden
