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
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.
