       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
