       TSS_RESULT Tspi_TPM_PcrExtend(TSS_HTPM       hTPM,              UINT32 ulPcrIndex,
                                     UINT32         ulPcrDataLength,   BYTE*  pbPcrData,

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 to be hashed by the TSS, 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
