       shandle2, ESYS_TR shandle3, const TPM2B_DIGEST * authPolicy, TPMI_ALG_HASH hashAlg, TPMI_DH_PCR pcrNum)
       One-Call function for TPM2_PCR_SetAuthPolicy

       This function invokes the TPM2_PCR_SetAuthPolicy command in a one-call variant. This means the function
       will block until the TPM response is available. All input parameters are const. The memory for non-simple
       output parameters is allocated by the function implementation.

       Parameters
           esysContext The ESYS_CONTEXT.
           authHandle TPM2_RH_PLATFORM+{PP}.
           shandle1 Session handle for authorization of authHandle
           shandle2 Second session handle.
           shandle3 Third session handle.
           authPolicy The desired authPolicy.
           hashAlg The hash algorithm of the policy.
           pcrNum The PCR for which the policy is to be set.

       Return values
           TSS2_RC_SUCCESS if the function call was a success.
           TSS2_ESYS_RC_BAD_REFERENCE if the esysContext or required input pointers or required output handle
           references are NULL.
           TSS2_ESYS_RC_BAD_CONTEXT if esysContext corruption is detected.
           TSS2_ESYS_RC_MEMORY if the ESAPI cannot allocate enough memory for internal operations or return
           parameters.
           TSS2_ESYS_RC_BAD_SEQUENCE if the context has an asynchronous operation already pending.
           TSS2_ESYS_RC_INSUFFICIENT_RESPONSE if the TPM's response does not at least contain the tag, response
           length, and response code.
           TSS2_ESYS_RC_MALFORMED_RESPONSE if the TPM's response is corrupted.
           TSS2_ESYS_RC_RSP_AUTH_FAILED if the response HMAC from the TPM did not verify.
           TSS2_ESYS_RC_MULTIPLE_DECRYPT_SESSIONS if more than one session has the 'decrypt' attribute bit set.
           TSS2_ESYS_RC_MULTIPLE_ENCRYPT_SESSIONS if more than one session has the 'encrypt' attribute bit set.
           TSS2_ESYS_RC_BAD_TR if any of the ESYS_TR objects are unknown to the ESYS_CONTEXT or are of the wrong
           type or if required ESYS_TR objects are ESYS_TR_NONE.
           TSS2_ESYS_RC_NO_ENCRYPT_PARAM if one of the sessions has the 'encrypt' attribute set and the command
           does not support encryption of the first response parameter.
           TSS2_RCs produced by lower layers of the software stack may be returned to the caller unaltered
           unless handled internally.

       pcrNum)
       Asynchronous function for TPM2_PCR_SetAuthPolicy

       This function invokes the TPM2_PCR_SetAuthPolicy command in a asynchronous variant. This means the
       function will return as soon as the command has been sent downwards the stack to the TPM. All input
       parameters are const. In order to retrieve the TPM's response call Esys_PCR_SetAuthPolicy_Finish.

       Parameters
           esysContext The ESYS_CONTEXT.
           authHandle TPM2_RH_PLATFORM+{PP}.
           shandle1 Session handle for authorization of authHandle
           shandle2 Second session handle.
           shandle3 Third session handle.
           authPolicy The desired authPolicy.
           hashAlg The hash algorithm of the policy.
           pcrNum The PCR for which the policy is to be set.

       Return values
           ESYS_RC_SUCCESS if the function call was a success.
           TSS2_ESYS_RC_BAD_REFERENCE if the esysContext or required input pointers or required output handle
           references are NULL.
           TSS2_ESYS_RC_BAD_CONTEXT if esysContext corruption is detected.
           TSS2_ESYS_RC_MEMORY if the ESAPI cannot allocate enough memory for internal operations or return
           parameters.
           TSS2_RCs produced by lower layers of the software stack may be returned to the caller unaltered
           unless handled internally.
           TSS2_ESYS_RC_MULTIPLE_DECRYPT_SESSIONS if more than one session has the 'decrypt' attribute bit set.
           TSS2_ESYS_RC_MULTIPLE_ENCRYPT_SESSIONS if more than one session has the 'encrypt' attribute bit set.
           TSS2_ESYS_RC_BAD_TR if any of the ESYS_TR objects are unknown to the ESYS_CONTEXT or are of the wrong
           type or if required ESYS_TR objects are ESYS_TR_NONE.
           TSS2_ESYS_RC_NO_ENCRYPT_PARAM if one of the sessions has the 'encrypt' attribute set and the command
           does not support encryption of the first response parameter.

   TSS2_RC Esys_PCR_SetAuthPolicy_Finish (ESYS_CONTEXT * esysContext)
       Asynchronous finish function for TPM2_PCR_SetAuthPolicy

       This function returns the results of a TPM2_PCR_SetAuthPolicy command invoked via
       Esys_PCR_SetAuthPolicy_Finish. All non-simple output parameters are allocated by the function's
       implementation. NULL can be passed for every output parameter if the value is not required.

       Parameters
           esysContext The ESYS_CONTEXT.

       Return values
           TSS2_RC_SUCCESS on success
           ESYS_RC_SUCCESS if the function call was a success.
           TSS2_ESYS_RC_BAD_REFERENCE if the esysContext or required input pointers or required output handle
           references are NULL.
           TSS2_ESYS_RC_BAD_CONTEXT if esysContext corruption is detected.
           TSS2_ESYS_RC_MEMORY if the ESAPI cannot allocate enough memory for internal operations or return
           parameters.
           TSS2_ESYS_RC_BAD_SEQUENCE if the context has an asynchronous operation already pending.
           TSS2_ESYS_RC_TRY_AGAIN if the timeout counter expires before the TPM response is received.
           TSS2_ESYS_RC_INSUFFICIENT_RESPONSE if the TPM's response does not at least contain the tag, response
           length, and response code.
           TSS2_ESYS_RC_RSP_AUTH_FAILED if the response HMAC from the TPM did not verify.
           TSS2_ESYS_RC_MALFORMED_RESPONSE if the TPM's response is corrupted.
           TSS2_RCs produced by lower layers of the software stack may be returned to the caller unaltered
           unless handled internally.
