2 The Barry library has the following exception hierarchy:
15 All specific USB error exceptions will be derived from
16 this class. Where possible, this class also stores the
17 specific return code from the libusb API, to allow
18 fine grained error handling.
21 All specific Barry error exceptions will be derived from
22 this class. This can be thrown from anywhere inside Barry.
25 There is also the remote possibility that there will be memory
26 exceptions from a call to 'new'. In that case, std::bad_alloc
27 will be thrown by the standard C++ libraries. Barry does not
31 Assert-like errors will cause std::logic_error to be thrown.
32 Barry does sometimes throw these, but they should be be
35 All of the above exceptions (from std, Barry, and Usb namespaces)
36 are derived from std::exception, so they can all be caught in one
37 statement for the efficient and lazy. :-)
