 ## -description
+
 Copies a source stream to a destination stream and waits for the copy operation to complete.
 
 ## -parameters
+
 ### -param source
+
 The stream to copy data from.
 
 ### -param destination
+
 The stream to copy data to.
 
 ## -returns
-The asynchronous operation.
+
+The byte writer operation. The first integer represents the number of bytes written. The second integer represents the progress of the write operation.
 
 ## -remarks
+
 The CopyAndCloseAsync method is similar to [CopyAsync](randomaccessstream_copyasync_1577084715.md) but also calls and waits for [FlushAsync](ioutputstream_flushasync_491532439.md) and [Close](/windows/desktop/api/windows.foundation/nf-windows-foundation-iclosable-close) on the output stream before its asynchronous operation completes.
