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.

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.
