 /*! \page errors Error Handling
 
-RtAudio no longer makes use of C++ exceptions.  Instead, the functions RtAudio::openStream(), RtAudio::startStream(), RtAudio::stopStream(), RtAudio::abortStream()) return an RtAudioErrorType variable, which will be RTAUDIO_NO_ERROR when successful. Details of the error can be obtained using an error callback function or by calling the RtAudio::getErrorText() function. In other cases, a warning message may be displayed and an appropriate value is returned.  For example, if a system error occurs when processing the RtAudio::getDeviceCount() function, the return value is zero.  In such a case, the user cannot expect to make use of most other RtAudio functions because no devices are available (and thus a stream cannot be opened).  A client can call the function RtAudio::showWarnings() with a boolean argument to enable or disable the printing of warning messages to <tt>stderr</tt>.  By default, warning messages are displayed.  There is a protected RtAudio method, error(), that can be modified to globally control how these messages are handled and reported.

Any non-zero return value from those functions indicates an error has occurred. If an RtAudioErrorCallback() function has been set, the #RtAudioErrorType and textual details will be provided through that function. One can also obtain the last error message by calling the RtAudio::getErrorText() function.

-The RtAudio::openStream() function attempts to open a stream with a specified set of parameter values.  In the above example, we attempt to open a two channel playback stream using the default output device, 32-bit floating point data, a sample rate of 44100 Hz, and a frame rate of 256 sample frames per output buffer.  If the user specifies an invalid parameter value (such as an unsupported sample rate or an invalid device ID), a non-zero RtAudioErrorType value of RTAUDIO_INVALID_PARAMETER (or perhaps RTAUDIO_INVALID_USE) is returned. If a system error occurs when attempting to open the stream, an RtAudioErrorType of RTAUDIO_SYSTEM_ERROR is returned. In either case, a descriptive error message can be retrieved using the RtAudio::getErrorText() function.

-RtAudio provides four signed integer and two floating point data formats which can be specified using the RtAudioFormat parameter values mentioned earlier.  If the opened device does not natively support the given format, RtAudio will automatically perform the necessary data format conversion.
+RtAudio provides four signed integer and two floating point data formats that can be specified using the RtAudioFormat parameter values mentioned earlier.  If the opened device does not natively support the given format, RtAudio will automatically perform the necessary data format conversion.
 
 The \c bufferFrames parameter specifies the desired number of sample frames that will be written to and/or read from a device per write/read operation.  This parameter can be used to control stream latency though there is no guarantee that the passed value will be that used by a device.  In general, a lower \c bufferFrames value will produce less latency but perhaps less robust performance.  A value of zero can be specified, in which case the smallest allowable value will be used.  The \c bufferFrames parameter is passed as a pointer and the actual value used by the stream is set during the device setup procedure.  \c bufferFrames values should be a power of two.  Optimal and allowable buffer values tend to vary between systems and devices.  Stream latency can also be controlled via the optional RtAudio::StreamOptions member \c numberOfBuffers (not used in the example above), though this tends to be more system dependent.  In particular, the \c numberOfBuffers parameter is ignored when using the OS-X Core Audio, Jack, and the Windows ASIO APIs.
 
 As noted earlier, the device capabilities reported by a driver or underlying audio API are not always accurate and/or may be dependent on a combination of device settings (for example, higher sample rates may reduce the maximum number of channels).  Because of this, RtAudio does not attempt to query a device's capabilities or use previously reported values when opening a device.  Instead, RtAudio simply attempts to set the given parameters on a specified device and then checks whether the setup is successful or not.
 
-The RtAudioCallback parameter above is a pointer to a user-defined function that will be called whenever the audio system is ready for new output data or has new input data to be read.  Further details on the use of a callback function are provided in the next section.

 Several stream options are available to fine-tune the behavior of an audio stream.  In the example above, we specify that data will be written by the user in a \e non-interleaved format via the RtAudio::StreamOptions member \c flags.  That is, all \c bufferFrames of the first channel should be written consecutively, followed by all \c bufferFrames of the second channel.  By default (when no option is specified), RtAudio expects data to be written in an \e interleaved format.
