Windows.Storage.Streams.IInputStream.readAsync(buffer, count, options).done( /* Your success and error handlers */ );
A buffer that may be used to return the bytes that are read. The return value contains the buffer that holds the results.
- unsigned int UInt32 UInt32 UInt32
The number of bytes to read that is less than or equal to the Capacity value.
Specifies the type of the asynchronous read operation.
The asynchronous operation.
Always read data from the buffer returned in the IAsyncOperationWithProgress(IBuffer, UInt32). Don't assume that the input buffer contains the data. Depending on the implementation, the data that's read might be placed into the input buffer, or it might be returned in a different buffer. For the input buffer, you don't have to implement the IBuffer interface. Instead, you can create an instance of the Buffer class.
