<P>
<dl><dt><b><a name='l2h-3282'><tt class='function'>locking</tt></a></b> (<var>fd, mode, nbytes</var>)
<dd>
  Lock part of a file based on a file descriptor from the C runtime.
  Raises <tt class="exception">IOError</tt> on failure.
</dl>

<P>
<dl><dt><b><a name='l2h-3283'><tt class='function'>setmode</tt></a></b> (<var>fd, flags</var>)
<dd>
  Set the line-end translation mode for the file descriptor <var>fd</var>.
  To set it to text mode, <var>flags</var> should be <tt class="constant">os.O_TEXT</tt>;
  for binary, it should be <tt class="constant">os.O_BINARY</tt>.
</dl>

<P>
<dl><dt><b><a name='l2h-3284'><tt class='function'>open_osfhandle</tt></a></b> (<var>handle, flags</var>)
<dd>
  Create a C runtime file descriptor from the file handle
  <var>handle</var>.  The <var>flags</var> parameter should be a bit-wise OR of
  <tt class="constant">os.O_APPEND</tt>, <tt class="constant">os.O_RDONLY</tt>, and
  <tt class="constant">os.O_TEXT</tt>.  The returned file descriptor may be used as a
  parameter to <tt class="function">os.fdopen()</tt> to create a file object.
</dl>

<P>
<dl><dt><b><a name='l2h-3285'><tt class='function'>get_osfhandle</tt></a></b> (<var>fd</var>)
<dd>
