Description

Forces any pending output from output-stream's buffers to its destination. Even if the stream is asynchronous, this call waits for all writes to complete. If synchronize? is true, also flushes the operating system's write cache for the file so that all data is physically written to disk. This should only be needed if you're concerned about system failure causing loss of data.
