cloudsync_network_check_changes()

Data isolation: Ensure users only access what they’re authorized to see.
Built-in privacy: Security policies are enforced at the database level.
Simplified development: Reduce or eliminate complex permission logic in your application code.

Description: Checks the remote server for new changes and applies them to the local database.

If a package of new changes is already available for the local site, the server returns it immediately, and the changes are applied. If no package is ready, the server returns an empty response and starts an asynchronous process to prepare a new package. This new package can be retrieved with a subsequent call to this function.

This function is designed to be called periodically to keep the local database in sync. To force an update and wait for changes (with a timeout), use cloudsync_network_sync(wait_ms, max_retries).

If the network is misconfigured or the remote server is unreachable, the function returns an error. On success, it returns SQLITE_OK, and the return value indicates how many changes were downloaded and applied.

Parameters: None.

Returns: The number of changes downloaded. Errors are reported via the SQLite return code.

Errors: See Network Errors for common error conditions.

Example:

SELECT cloudsync_network_check_changes();
