- 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
Windows.Foundation.IAsyncOperationWithProgress<Windows.Storage.Streams.IBuffer,unsigned int>
IAsyncOperationWithProgress<IBuffer,uint32_t>
The asynchronous operation.
