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 that is less than or equal to the Capacity value.

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.
