CONTENTS

SYNOPSIS


#include <tss/platform.h> 

#include <tss/tcpa_defines.h> 

#include <tss/tcpa_typedef.h> 

#include <tss/tcpa_struct.h>

#include <tss/tspi.h> 

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 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
