@section tut_init1 Initializing PortAudio

Before making any other calls to PortAudio, you 'must' call Pa_Initialize(). This will trigger a scan of available devices which can be queried later. Like most PA functions, it will return a result of type paError. If the result is not paNoError, then an error has occurred.
@code
err = Pa_Initialize();
if( err != paNoError ) goto error;
@endcode

You can get a text message that explains the error message by passing it to Pa_GetErrorText( err ). For Example:

@code
printf(  "PortAudio error: %s\n", Pa_GetErrorText( err ) );
@endcode

It is also important, when you are done with PortAudio, to Terminate it:

@code
err = Pa_Terminate();
if( err != paNoError )
   printf(  "PortAudio error: %s\n", Pa_GetErrorText( err ) );
@endcode
