In a C++ application, you have a stream of data being logged...
- Write to a temporary file first
- Use std::ofstream::flush after every write
- Use file locking mechanisms
- Implement journaling or write-ahead logging
Implementing journaling or write-ahead logging means changes are first logged to a separate, sequential log. In case of failures, this log can be used to bring the file back to a consistent state. This provides a safeguard against data corruption or loss during unforeseen events.
