How to send a sync_log_storage request and wait for a response

Hi,

I've been trying to use the DLT control interface to request that the DLT daemon sync its logs (using `dlt_client_send_ctrl_msg()` with a `DltServiceOfflineLogstorage` payload), but I recently noticed that this function returns as soon as the request is sent, not when it receives confirmation that the logs have finished syncing.

Looking through DLT Daemon's source code, it seems that a message with a `DltServiceResponse` payload it sent.

How can I wait until it has been received?

libdlt's dlt_client.h has a `dlt_client_main_loop()`, which, when combined with `dlt_client_register_message_callback()` and `dlt_client_register_fetch_next_message_callback()` would give me access to any messages that get received, and gives me a way to terminate the loop.

Is this the best way to wait until a response is received, and is there a good way to make this time out if the DLT daemon stops responding?

Thanks,

Jonathan
