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.
