Function Documentation

◆ Esys_Startup()

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
[in,out]esysContextThe ESYS_CONTEXT.
[in]startupTypeTPM2_SU_CLEAR or TPM2_SU_STATE.
Return values
TSS2_RC_SUCCESSif the function call was a success.
TSS2_ESYS_RC_BAD_REFERENCEif the esysContext or required input pointers or required output handle references are NULL.
TSS2_ESYS_RC_BAD_CONTEXTif esysContext corruption is detected.
TSS2_ESYS_RC_MEMORYif the ESAPI cannot allocate enough memory for internal operations or return parameters.
TSS2_ESYS_RC_BAD_SEQUENCEif the context has an asynchronous operation already pending.
TSS2_ESYS_RC_INSUFFICIENT_RESPONSEif the TPM's response does not at least contain the tag, response length, and response code.
TSS2_ESYS_RC_MALFORMED_RESPONSEif the TPM's response is corrupted.
TSS2_ESYS_RC_RSP_AUTH_FAILEDif the response HMAC from the TPM did not verify.
TSS2_RCsproduced by lower layers of the software stack may be returned to the caller unaltered unless handled internally.

◆ Esys_Startup_Async()

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
[in,out]esysContextThe ESYS_CONTEXT.
[in]startupTypeTPM2_SU_CLEAR or TPM2_SU_STATE.
Return values
ESYS_RC_SUCCESSif the function call was a success.
TSS2_ESYS_RC_BAD_REFERENCEif the esysContext or required input pointers or required output handle references are NULL.
TSS2_ESYS_RC_BAD_CONTEXTif esysContext corruption is detected.
TSS2_ESYS_RC_MEMORYif the ESAPI cannot allocate enough memory for internal operations or return parameters.
TSS2_RCsproduced by lower layers of the software stack may be returned to the caller unaltered unless handled internally.

◆ Esys_Startup_Finish()

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
[in,out]esysContextThe ESYS_CONTEXT.
Return values
TSS2_RC_SUCCESSon success
ESYS_RC_SUCCESSif the function call was a success.
TSS2_ESYS_RC_BAD_REFERENCEif the esysContext or required input pointers or required output handle references are NULL.
TSS2_ESYS_RC_BAD_CONTEXTif esysContext corruption is detected.
TSS2_ESYS_RC_MEMORYif the ESAPI cannot allocate enough memory for internal operations or return parameters.
TSS2_ESYS_RC_BAD_SEQUENCEif the context has an asynchronous operation already pending.
TSS2_ESYS_RC_TRY_AGAINif the timeout counter expires before the TPM response is received.
TSS2_ESYS_RC_INSUFFICIENT_RESPONSEif the TPM's response does not at least contain the tag, response length, and response code.
TSS2_ESYS_RC_RSP_AUTH_FAILEDif the response HMAC from the TPM did not verify.
TSS2_ESYS_RC_MALFORMED_RESPONSEif the TPM's response is corrupted.
TSS2_RCsproduced by lower layers of the software stack may be returned to the caller unaltered unless handled internally.
