Definition

Namespace:
Windows.Storage.Streams

Overloads

CopyAsync(IInputStream, IOutputStream)

Copies a source stream to a destination stream.
CopyAsync(IInputStream, IOutputStream, UInt64)

Copies the specified number of bytes from a source stream to a destination stream.

CopyAsync(IInputStream, IOutputStream)

Edit

Copies a source stream to a destination stream.

function copyAsync(source, destination)
Public Shared Function CopyAsync (source As IInputStream, destination As IOutputStream) As IAsyncOperationWithProgress(Of ULong, ULong)

Parameters

source
IInputStream

The stream to copy data from.

destination
IOutputStream

The stream to copy data to.

Returns

IAsyncOperationWithProgress<UInt64,UInt64>

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

IAsyncOperationWithProgress<uint64_t,uint64_t>

The byte writer operation. The first integer represents the number of bytes written. The second integer represents the progress of the write operation.
