Summary
Synchronizes an output stream with the application state.

- An instance of
<stream>.

Module
streams
Description
Forces any pending output from output-stream's buffers to its destination. Before returning to its caller, synchronize-output also attempts to ensure that the output reaches the stream's destination before, thereby synchronizing the output destination with the application state.
When creating new stream classes it may be necessary to add a method to the synchronize-output function, even though it is not part of the Stream Extension Protocol.
