tlv_transaction_check_status_t tlv_use_case_transaction_check	(	const buffer_t *	payload,
		tlv_transaction_check_out_t *	out

Parse a Transaction Check TLV payload.

Parses the provided TLV payload, verifies the PKI signature, and extracts the simulation result into the output structure.

Parameters

[in]	payload	Pointer to the buffer containing the TLV payload data.
[out]	out	Pointer to the structure where the parsed Transaction Check result will be stored.

Returns

Status code indicating the result of the operation. See tlv_transaction_check_status_t for possible values.
