title: Getting an array of bytes out of Windows::Storage::Streams::IBuffer
body: <p>I have an object that implements the interface <code>Windows::Storage::Streams::IBuffer</code>, and I want to get an array of bytes out of it, however while looking at the documentation this interface looks pretty useless, and the documentation does not offer any reference to any other class that could be combined with this interface to achieve my purpose. All I have found so far with google is a reference to the .Net class <a href="http://msdn.microsoft.com/en-us/library/system.runtime.interopservices.windowsruntime.windowsruntimebufferextensions(v=vs.110).aspx" rel="noreferrer">WindowsRuntimeBufferExtensions</a> but I am using C++ so this is also a dead end. </p>
  
  <p>Can someone give a hint on how to get an array of bytes from <code>Windows::Storage::Streams::IBuffer</code> in C++?</p>
