StreamedFileDataRequest.WriteAsync(IBuffer) Method

Definition

Namespace:

Windows.Storage

Writes data from a buffer to the current stream.

public:
 virtual IAsyncOperationWithProgress<unsigned int, unsigned int> ^ WriteAsync(IBuffer ^ buffer) = WriteAsync;

IAsyncOperationWithProgress<uint32_t, uint32_t> WriteAsync(IBuffer const& buffer);

public IAsyncOperationWithProgress<uint,uint> WriteAsync(IBuffer buffer);

function writeAsync(buffer)

Public Function WriteAsync (buffer As IBuffer) As IAsyncOperationWithProgress(Of UInteger, UInteger)

Parameters

buffer

IBuffer

The buffer that contains the data to write.

Returns

IAsyncOperationWithProgress<UInt32,UInt32>

Windows.Foundation.IAsyncOperationWithProgress<unsigned int,unsigned int>

IAsyncOperationWithProgress<uint32_t,uint32_t>

When this method completes, it returns the number of bytes (type UInt32) that were written to the stream. If the app specifies a function to monitor progress, that function receives the number of bytes (type UInt32) written so far.
