Function Documentation

   TSS2_RC Esys_Startup (ESYS_CONTEXT * esysContext, TPM2_SU startupType)
       One-Call function for TPM2_Startup

       This function invokes the TPM2_Startup 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.
           startupType TPM2_SU_CLEAR or TPM2_SU_STATE.

       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_RCs produced by lower layers of the software stack may be returned to the caller unaltered
           unless handled internally.

   TSS2_RC Esys_Startup_Async (ESYS_CONTEXT * esysContext, TPM2_SU startupType)
       Asynchronous function for TPM2_Startup

       This function invokes the TPM2_Startup 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_Startup_Finish.

       Parameters
           esysContext The ESYS_CONTEXT.
           startupType TPM2_SU_CLEAR or TPM2_SU_STATE.

       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_RC Esys_Startup_Finish (ESYS_CONTEXT * esysContext)
       Asynchronous finish function for TPM2_Startup

       This function returns the results of a TPM2_Startup command invoked via Esys_Startup_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.
