title: What DLLMain lpReserved parameter really mean?
body: <p>One of well-known <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/ms682583%28v=vs.85%29.aspx" rel="nofollow">DLLMain</a> function parameters is <em>LPVOID lpvReserved</em>.
  From MSDN documentation:</p>
  
  <blockquote>
    <p>If fdwReason is DLL_PROCESS_ATTACH, lpvReserved is NULL for dynamic
    loads and non-NULL for static loads.</p>
  </blockquote>
