       event log.

       TSS_RESULT Tspi_TPM_PcrExtend(TSS_HTPM       hTPM,              UINT32 ulPcrIndex,
                                     UINT32         ulPcrDataLength,   BYTE*  pbPcrData,
                                     TSS_PCR_EVENT* pPcrEvent,
                                     UINT32*        pulPcrValueLength, BYTE** prgbPcrValue);

DESCRIPTION
       Tspi_TPM_PcrExtend extends a PCR register and writes the PCR event log
       if one is supplied by the user.

PARAMETERS
   hTPM
       The hTPM parameter is used to specify the handle of the TPM object. The
       command to get the TPM to test itself will be sent here.

   ulPcrIndex
       The ulPcrIndex parameter is the index of the PCR to extend.

   ulPcrDataLength
       The ulPcrDataLength parameter is the length in bytes of the pbPcrData
       parameter.

   pbPcrData
       The pbPcrData parameter is a pointer to data which will be used in the
       extend operation.

   pPcrEvent
       The pPcrEvent parameter is the TSS_PCR_EVENT structure to be passed to
       the TCS to record the extend event. If pPcrEvent is not NULL, the
       application should fill out the members of the structure that it cares
       about.

   pulPcrValueLength
       The pulPcrValueLength parameter receives the length in bytes of the
       prgbPcrValue parameter.

   prgbPcrValue
       The prgbPcrValue receives a pointer to the memory block containing the
       PCR data after the extend operation.

RETURN CODES
       Tspi_TPM_PcrExtend returns TSS_SUCCESS on success, otherwise one of the
       following values is returned:

       TSS_E_INVALID_HANDLE
              hTPM 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.

CONFORMING TO
       Tspi_TPM_PcrExtend conforms to the Trusted Computing Group Software
       Specification version 1.1 Golden
