IOutputStream IOutputStream IOutputStream IOutputStream Interface

Flushes data asynchronously in a sequential stream.

public : IAsyncOperation<PlatForm::Boolean> FlushAsync()public IAsyncOperation<bool> FlushAsync()Public Function FlushAsync() As IAsyncOperation( Of bool )// You can use this method in JavaScript.

Remarks

The FlushAsync method may produce latencies and does not always guarantee durable and coherent storage of data. It's generally recommended to avoid this method if possible.

Writes data asynchronously in a sequential stream.

public : IAsyncOperationWithProgress<unsigned int, unsigned int> WriteAsync(IBuffer buffer)public IAsyncOperationWithProgress<uint, uint> WriteAsync(IBuffer buffer)Public Function WriteAsync(buffer As IBuffer) As IAsyncOperationWithProgress( Of uint, uint )// You can use this method in JavaScript.

Remarks

Some stream implementations support queuing of write operations. In this case, the asynchronous execution of the WriteAsync method does not complete until the FlushAsync method has completed. For the buffer parameter, you don't have to implement the IBuffer interface. Instead, you can create an instance of the Buffer class or create a buffer by using methods in the CryptographicBuffer class.

Also consider writing a buffer into an IOutputStream by using the WriteBuffer method of the DataWriter class.
