 In most cases you won't have to rewrite much, if any, code. The Native
 Client-specific tools, such as ``pnacl-clang++`` or ``x86_64-nacl-g++``,
 take care of most of the necessary changes. You may need to make some
 changes to your operating system calls and interactions with external
 devices to work with the web. Porting existing Linux libraries is
 generally straightforward, with large libraries often requiring no
 source change.
 
 The following kinds of code may be more challenging to port:
 
-* Code that does direct `TCP <pepper_stable/cpp/classpp_1_1_u_d_p_socket>`_ or
+* Code that does direct `TCP <pepper_stable/cpp/classpp_1_1_t_c_p_socket>`_ or
   `UDP <pepper_stable/cpp/classpp_1_1_u_d_p_socket>`_ networking. For security
   reasons these APIs are only available to `packaged applications
   </apps/about_apps>`_ after asking for the appropriate permissions, not on the
   open web. Native Client is otherwise restricted to the networking APIs
   available in the browser. You may want to use to `nacl_io library <nacl_io>`_
   to use POSIX-like sockets.
 * Code that creates processes, including UNIX ``fork``, won't function
   as-is. However, threads are supported. You can nonetheless create new
   ``<embed>`` tags in your HTML page to launch new PNaCl processes, even using
   new ``.pexe`` files that your existing ``.pexe`` saved in a local
