<h2>

|
Terminating PortAudio</h2>
|
|
|
|
<blockquote>You can start and stop a stream as many times as you like.
|
|
But when you are done using it, you should close it by calling:</blockquote>
|
|
|
|
<blockquote>
|
|
<blockquote>
|
|
<pre>err = Pa_CloseStream( stream );
|
|
if( err != paNoError ) goto error;</pre>
|
|
</blockquote>
|
|
Then when you are done using PortAudio, you should terminate the whole
|
|
system by calling:
|
|
<blockquote>
|
|
<pre>Pa_Terminate();</pre>
|
|
</blockquote>
|
|
That's basically it. You can now write an audio program in 'C' that will
|
|
run on multiple platforms, for example PCs and Macintosh.
|
|
<p>In the rest of the tutorial we will look at some additional utility
|
|
functions, and a different way of using PortAudio that does not require
|
|
the use of a callback function.</blockquote>
