Chris@559 2 /*! \class RtError
Chris@559 3 \brief Exception handling class for RtAudio & RtMidi.
Chris@559 4
Chris@559 5 The RtError class is quite simple but it does allow errors to be
Chris@559 6 "caught" by RtError::Type. See the RtAudio and RtMidi
Chris@559 7 documentation to know which methods can throw an RtError.
