Function Documentation

TSS2_RC Esys_Clear_Async (ESYS_CONTEXT * esysContext, ESYS_TR authHandle, ESYS_TR shandle1, ESYS_TR shandle2, ESYS_TR shandle3)
Asynchronous function for TPM2_Clear

This function invokes the TPM2_Clear 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_Clear_Finish.

Parameters

esysContext The ESYS_CONTEXT.
authHandle
TPM2_RH_LOCKOUT or TPM2_RH_PLATFORM+{PP}.
shandle1
Session handle for authorization of authHandle
shandle2
Second session handle.
shandle3
Third session handle.

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.
