There are several ways to throw exceptions with expy.
First of all, you can use @throws(...) to throw exceptions based on input and output of a function. Another possibility is to throw exceptions inside your function implementation, and upon return of your code, the wrapper function would return NULL after all necessary reference count management, if any exception is thrown by your function implementation code. Please also refer to the documentation of expy on exception handling here (it also includes how to create a custom exception, and how to manage exception inheritance):
