<H1><A NAME="SECTION006700000000000000000">
4.7 <tt class=module>cStringIO</tt> --
         Faster version of <tt class=module>StringIO</tt></A>
</H1>

<P>


<P>
The module <tt class=module>cStringIO</tt> provides an interface similar to that of
the <tt class=module><a href="module-StringIO.html">StringIO</a></tt> module.  Heavy use of <tt class=class>StringIO.StringIO</tt>
objects can be made more efficient by using the function
<tt class=function>StringIO()</tt> from this module instead.

<P>
Since this module provides a factory function which returns objects of
built-in types, there's no way to build your own version using
subclassing.  Use the original <tt class=module><a href="module-StringIO.html">StringIO</a></tt> module in that case.

<P>
The following data objects are provided as well:

<P>
<dl><dt><b><a name="l2h-708"><tt>InputType</tt></a></b>
<dd>
  The type object of the objects created by calling
  <tt class=function>StringIO</tt> with a string parameter.
</dl>

<P>
<dl><dt><b><a name="l2h-709"><tt>OutputType</tt></a></b>
<dd>
  The type object of the objects returned by calling
  <tt class=function>StringIO</tt> with no parameters.
</dl>

<P>
There is a C API to the module as well; refer to the module source for 
more information.
