title: WOW64_CONTEXT ContextFlags data member values?
body: <p>After looking through MSDN documentation of both <code>Wow64GetThreadContext</code> and <code>WOW64_CONTEXT</code> I have no idea what the possible values are for the <code>ContextFlags</code> data member of <code>WOW64_CONTEXT</code>. And <code>ContextFlags</code> is supposed to be set by the caller and it affects the context.</p>
  <blockquote>
  <p>lpContext [in, out] A WOW64_CONTEXT structure. The caller must initialize the ContextFlags member of this structure.</p>
  <p>The function retrieves a selective context based on the value of the ContextFlags member of the context structure.</p>
  </blockquote>
  <p>I found various macros starting with CONTEXT but none of them seem to have an effect. Any information would be appreciated.</p>
