/// C++ exceptions and is derived from std::exception for

|
/// easy exception handling and to ease integration with

/// other code.

|

/// To know what exceptions each function may throw, look up
|
|
/// the errors that can occur in the PortAudio documentation
|
|
/// for the equivalent functions.
|
|
///
|
|
/// Some functions are likely to throw an exception (such as
|
|
/// Stream::open(), etc) and these should always be called in
|
|
/// try{} catch{} blocks and the thrown exceptions should be
|
|
/// handled properly (ie. the application shouldn't just abort,
|
|
/// but merely display a warning dialog to the user or something).
|
|
/// However nearly all functions in PortAudioCpp are capable
|
|
/// of throwing exceptions. When a function like Stream::isStopped()
|
|
/// throws an exception, it's such an exceptional state that it's
|
|
/// not likely that it can be recovered. PaExceptions such as these
|
|
/// can ``safely'' be left to be handled by some outer catch-all-like
|
|
/// mechanism for unrecoverable errors.
