Tspi_TPM_PcrExtend - extend a PCR register and optionally write the PCR event log.

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

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

       Tspi_TPM_PcrExtend - extend a PCR register and optionally write the PCR event log.

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  opera‐
       tion.

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.
