Returns an asynchronous byte reader object.

public:
 virtual IAsyncOperationWithProgress<IBuffer ^, unsigned int> ^ ReadAsync(IBuffer ^ buffer, unsigned int count, InputStreamOptions options) = ReadAsync;

IAsyncOperationWithProgress<IBuffer, uint32_t> ReadAsync(IBuffer const& buffer, uint32_t const& count, InputStreamOptions const& options);

public IAsyncOperationWithProgress<IBuffer,uint> ReadAsync(IBuffer buffer, uint count, InputStreamOptions options);

function readAsync(buffer, count, options)

Public Function ReadAsync (buffer As IBuffer, count As UInteger, options As InputStreamOptions) As IAsyncOperationWithProgress(Of IBuffer, UInteger)

Parameters

buffer: IBuffer

The buffer into which the asynchronous read operation places the bytes that are read.

count: UInt32
unsigned int

uint32_t

The number of bytes to read.

options: InputStreamOptions

Specifies the type of the asynchronous read operation.

Returns

IAsyncOperationWithProgress<IBuffer,UInt32>

Windows.Foundation.IAsyncOperationWithProgress<Windows.Storage.Streams.IBuffer,unsigned int>

IAsyncOperationWithProgress<IBuffer,uint32_t>

The asynchronous operation.
