Function Documentation

   TSS2_RC Esys_PolicyCommandCode (ESYS_CONTEXT * esysContext, ESYS_TR policySession, ESYS_TR
       shandle1, ESYS_TR shandle2, ESYS_TR shandle3, TPM2_CC code)
       One-Call function for TPM2_PolicyCommandCode

       This function invokes the TPM2_PolicyCommandCode 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.
           policySession Handle for the policy session being extended.
           shandle1 First session handle.
           shandle2 Second session handle.
           shandle3 Third session handle.
           code The allowed commandCode.

       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_DECRYPT_PARAM if one of the sessions has the 'decrypt' attribute set
           and the command does not support encryption of the first command parameter.
           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.

   TSS2_RC Esys_PolicyCommandCode_Async (ESYS_CONTEXT * esysContext, ESYS_TR policySession,
       ESYS_TR shandle1, ESYS_TR shandle2, ESYS_TR shandle3, TPM2_CC code)
       Asynchronous function for TPM2_PolicyCommandCode

       This function invokes the TPM2_PolicyCommandCode 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_PolicyCommandCode_Finish.

       Parameters
           esysContext The ESYS_CONTEXT.
           policySession Handle for the policy session being extended.
           shandle1 First session handle.
           shandle2 Second session handle.
           shandle3 Third session handle.
           code The allowed commandCode.

       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_DECRYPT_PARAM if one of the sessions has the 'decrypt' attribute set
           and the command does not support encryption of the first command parameter.
           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_PolicyCommandCode_Finish (ESYS_CONTEXT * esysContext)
       Asynchronous finish function for TPM2_PolicyCommandCode

       This function returns the results of a TPM2_PolicyCommandCode command invoked via
       Esys_PolicyCommandCode_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.
