<h2>
Initializing PortAudio</h2>
<blockquote>Before making any other calls to PortAudio, you must call <tt>Pa_Initialize</tt>().
This will trigger a scan of available devices which can be queried later.
Like most PA functions, it will return a result of type <tt>paError</tt>.
If the result is not <tt>paNoError</tt>, then an error has occurred.
<blockquote>
<pre>err = Pa_Initialize();
if( err != paNoError ) goto error;</pre>
</blockquote>
You can get a text message that explains the error message by passing it
to
<blockquote>
<pre>printf( "PortAudio error: %s\n", Pa_GetErrorText( err ) );</pre>
</blockquote>
</blockquote>
