-Redirecting output to the JavaScript console

[Mark Seaborn, 2014/09/03 15:16:39]

The generated HTML is checked in. :-(  You need to run "make chromesite_rst"
from native_client_sdk/src/doc/ to regenerate it.

-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-You can also cause output from printf statements in your C/C++ code to be
-relayed to the JavaScript side of your application through the Pepper messaging
-system, where you can then write the output to the JavaScript console. Follow
-these steps:
-
-#. Set the ``NACL_EXE_STDOUT`` and ``NACL_EXE_STDERR`` environment variables as
-   follows:
-
-   * ``NACL_EXE_STDOUT=DEBUG_ONLY:dev://postmessage``
-   * ``NACL_EXE_STDERR=DEBUG_ONLY:dev://postmessage``
-
-   These settings tell Native Client to use ``PostMessage()`` to send output
-   that your Native Client module writes to stdout and stderr to the JavaScript
-   side of your application.
-
-#. Register a JavaScript handler to receive messages from your Native Client
-   module:
-
-   .. naclcode::
-
-     <div id="nacl_container">
-       <script type="text/javascript">
-         var container = document.getElementById('nacl_container');
-         container.addEventListener('message', handleMessage, true);
-       </script>
-       <embed id="nacl_module"
-              src="my_application.nmf"
-              type="application/x-nacl" />
-     </div>
-
-#. Implement a simple JavaScript handler that logs the messages it receives to
-   the JavaScript console:
-
-   .. naclcode::
-
-     function handleMessage(message_event) {
-       console.log(message_event.data);
-     }
-
-   This handler works in the simple case where the only messages your Native
-   Client module sends to JavaScript are messages with the output from stdout
-   and stderr. If your Native Client module also sends other messages to
-   JavaScript, your handler will need to be more complex.
-
-   Once you've implemented a message handler and set up the environment
-   variables as described above, you can check the JavaScript console to see
-   output that your Native Client module prints to stdout and stderr. Keep in
-   mind that your module makes a call to ``PostMessage()`` every time it flushes
-   stdout or stderr.  Your application's performance will degrade considerably
-   if your module prints and flushes frequently, or if it makes frequent Pepper
-   calls to begin with (e.g., to render).
