title: ReadDirectoryChangesW not recognize more than 1 file addition
body: <p>I'm trying to monitor a directory using <code>ReadDirectoryChangesW</code>. Whenever a new file is added to the directory I monitor the application should print it's name. The application works fine if I copy one file at a time, but if I try,lets say 2 files at a time, it recognize only one of them.</p>
  
  <p>I'm using this function synchronously.</p>
  
  <p>Here is the code:</p>
  
  <p>The handle to the directory:</p>
  
  <pre><code>HANDLE hDir = CreateFile( 
      "d:\\Detect", /* pointer to the file name */
      FILE_LIST_DIRECTORY,                /* access (read-write) mode */
      FILE_SHARE_READ|FILE_SHARE_DELETE,  /* share mode */
      NULL, /* security descriptor */
      OPEN_EXISTING, /* how to create */
      FILE_FLAG_BACKUP_SEMANTICS, /* file attributes */
      NULL /* file with attributes to copy */
  );
  </code></pre>
  
  <p>And <code>ReadDirectoryChangesW</code>:</p>
  
  <pre><code>ReadDirectoryChangesW(hDir,&amp;Buffer,sizeof(Buffer),FALSE,
      FILE_NOTIFY_CHANGE_SECURITY|
      FILE_NOTIFY_CHANGE_CREATION|
      FILE_NOTIFY_CHANGE_LAST_ACCESS|
      FILE_NOTIFY_CHANGE_LAST_WRITE|
      FILE_NOTIFY_CHANGE_SIZE|
      FILE_NOTIFY_CHANGE_ATTRIBUTES|
      FILE_NOTIFY_CHANGE_DIR_NAME|
      FILE_NOTIFY_CHANGE_FILE_NAME,&amp;bytesReturned,NULL,NULL);
  </code></pre>
