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> <font size=+2><a href="http://www.portaudio.com/">home</a> | <a href="pa_tutorial.html">contents</a> | <a href="pa_tut_run.html">previous</a> | <a href="pa_tut_util.html">next</a></font> </body> </html>
