Luna::flush_log_to_file
void flush_log_to_file()
Flushes the log-to-file cache and writes all cached logs to the log file.
Remark
For performance reasons, when logging-to-file is enabled, log messages will be cached in a log buffer and written to the log file in one call when the buffer is full. The user can also call flush_log_to_file to flush the cache manually when needed.
