One-Call function for Fapi_Initialize

Initializes a FAPI_CONTEXT that holds all the state and metadata information during an interaction with the TPM.

Parameters

context The FAPI_CONTEXT
uri Unused in this version of the FAPI. Must be NULL

Return values

TSS2_RC_SUCCESS if the function call was a success.
TSS2_FAPI_RC_BAD_REFERENCE if context is NULL.
TSS2_FAPI_RC_BAD_VALUE if uri is not NULL.
TSS2_FAPI_RC_IO_ERROR if the data cannot be saved.
TSS2_FAPI_RC_MEMORY if the FAPI cannot allocate enough memory for internal operations or return parameters.
TSS2_FAPI_RC_TRY_AGAIN if an I/O operation is not finished yet and this function needs to be called again.
TSS2_FAPI_RC_BAD_SEQUENCE if the context has an asynchronous operation already pending.
TSS2_FAPI_RC_GENERAL_FAILURE if an internal error occurred.
TSS2_FAPI_RC_BAD_PATH if a path is used in inappropriate context or contains illegal characters.
TSS2_ESYS_RC_* possible error codes of ESAPI.

Asynchronous function for Fapi_Initialize
