IOutputStream IOutputStream IOutputStream Interface
Represents a sequential stream of bytes to be written.

FlushAsync() FlushAsync() FlushAsync()
Flushes data asynchronously in a sequential stream.
public : IAsyncOperation<PlatForm::Boolean> FlushAsync()
public IAsyncOperation<bool> FlushAsync()
Public Function FlushAsync() As IAsyncOperation( Of bool )
The stream flush operation.
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.
WriteAsync(IBuffer) WriteAsync(IBuffer) WriteAsync(IBuffer)
Writes data asynchronously in a sequential stream.
public : IAsyncOperationWithProgress<unsigned short, unsigned short> WriteAsync(IBuffer buffer)
public IAsyncOperationWithProgress<uint, uint> WriteAsync(IBuffer buffer)
Public Function WriteAsync(buffer As IBuffer) As IAsyncOperationWithProgress( Of uint, uint )
The byte writer operation.
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.
