Tspi_TPM_PcrRead(3)
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> #include <tss/tss_structs.h> #include <tss/tspi.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 containing 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 Specification version 1.1 Golden
