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/tss_typedef.h>
       #include <tss/tss_structs.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  containing  the  PCR  value  of  the  PCR  indicated  by
       ulPcrIndex.

RETURN CODES
       Tspi_PcrComposite_GetPcrValue returns TSS_SUCCESS on success, otherwise
       one of the following 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 Specification version 1.1 Golden
