title: How to cast IntPtr to byte*
body: <p>I'm calling a method via interop that returns an <code>out IntPtr</code> parameter. How can I get a <code>byte*</code> for this <code>IntPtr</code> so I can operate on it? I tried the following:</p>
  
  <pre><code>fixed(byte* ptr = (byte)myIntPtr)
  </code></pre>
  
  <p>but it didn't work. Any help would be appreciated!</p>
