Function Documentation

Fapi_NvExtend()

TSS2_RC Fapi_NvExtend	(	FAPI_CONTEXT *	context,
		char const *	nvPath,
		uint8_t const *	data,
		size_t	dataSize,
		char const *	logData
	)

One-Call function for Fapi_NvExtend

Performs an extend operation on an NV index with the type extend.

Parameters

[in,out]	context	the FAPI context
[in]	nvPath	The path to the NV index that is extended
[in]	data	The data to extend on the NV index
[in]	dataSize	The size of the data to extend. Must be smaller than 1024
[in]	logData	A JSON representation of the data that is written to the event log. May be NULL

Return values

TSS2_RC_SUCCESS	if the function call was a success.
TSS2_FAPI_RC_BAD_REFERENCE	if context, nvPath, or data is NULL.
TSS2_FAPI_RC_BAD_CONTEXT	if context corruption is detected.
TSS2_FAPI_RC_BAD_PATH	if nvPath is not found.
TSS2_FAPI_RC_NV_WRONG_TYPE	if the NV is not an extendable index.
TSS2_FAPI_RC_POLICY_UNKNOWN	if the policy is unknown.
TSS2_FAPI_RC_BAD_SEQUENCE	if the context has an asynchronous operation already pending.
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_NO_TPM	if FAPI was initialized in no-TPM-mode via its config file.
TSS2_FAPI_RC_BAD_VALUE	if an invalid value was passed into the function.
TSS2_FAPI_RC_PATH_NOT_FOUND	if a FAPI object path was not found during authorization.
TSS2_FAPI_RC_KEY_NOT_FOUND	if a key was not found.
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_GENERAL_FAILURE	if an internal error occurred.
TSS2_FAPI_RC_AUTHORIZATION_UNKNOWN	if a required authorization callback is not set.
TSS2_FAPI_RC_AUTHORIZATION_FAILED	if the authorization attempt fails.
TSS2_ESYS_RC_*	possible error codes of ESAPI.
TSS2_FAPI_RC_NOT_PROVISIONED	FAPI was not provisioned.

Fapi_NvExtend_Async()

TSS2_RC Fapi_NvExtend_Async	(	FAPI_CONTEXT *	context,
		char const *	nvPath,
		uint8_t const *	data,
		size_t	dataSize,
		char const *	logData
	)

[in]	logData	A JSON representation of the data that is written to the event log. May be NULL

Return values

TSS2_RC_SUCCESS	if the function call was a success.

TSS2_FAPI_RC_BAD_PATH	if nvPath is not found.
TSS2_FAPI_RC_NV_WRONG_TYPE	if the NV is not an extendable index.
TSS2_FAPI_RC_POLICY_UNKNOWN	if the policy is unknown.
TSS2_FAPI_RC_BAD_SEQUENCE	if the context has an asynchronous operation already pending.
TSS2_FAPI_RC_IO_ERROR	if the data cannot be saved.
