Exercise 4: Handling Errors

---

In this exercise you will learn how to handle synchronous and asynchronous exceptions.

---

1.) Catch synchronous exception handling

Synchronous errors, such as failure to construct an object, are reported immediately by the runtime throwing an exception.

To catch synchronous exceptions simply wrap your application in a try catch block and catch a SYCL exception and print out the error message provided by the what member function.

2. ) Catch and asynchronous exceptions

Asynchronous errors, such as an error occurring during execution of a kernel on a device, are reported via user-supplied asynchronous error-handlers.

To catch asynchronous exceptions create an async handler using a lambda expression which takes an exception_list, iterates over it and rethrows the exceptions to be caught by the surrounding try-catch block.
