NAME
Tspi_TPM_PcrRead - read the value in a PCR register
SYNOPSIS
#include <tss/platform.h>
#include <tss/tcpa_defines.h>
#include <tss/tcpa_typedef.h>
#include <tss/tcpa_struct.h>
#include <tss/tss_typedef.h>

TSS_RESULT Tspi_TPM_PcrRead(TSS_HTPM hTPM, UINT32 ulPcrIndex,
UINT32* pulPcrValueLength, BYTE** prgbPcrValue);
DESCRIPTION
Tspi_TPM_PcrRead reads a PCR register to find the current values.
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 read.
pulPcrValueLength
The pulPcrValueLength parameter receives the length in bytes of the
prgbPcrValue parameter.
prgbPcrValue
The prgbPcrValue parameter receives a pointer to the memory block con-
taining the PCR data.
RETURN CODES
Tspi_TPM_PcrRead 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_PcrRead conforms to the Trusted Computing Group Software Spec-
ification version 1.1 Golden
