While this is always the case for Python functions, functions defined as C functions or ``cpdef``/``@ccall`` functions can return arbitrary C types, which do not have such a well-defined error return value. -Extra care must be taken to ensure Python exceptions are correctly -propagated from such functions. +By default Cython uses a dedicated return value to signal that an exception has been raised from non-external ``cpdef``/``@ccall`` +functions. However, how Cython handles exceptions from these functions can be changed if needed. A ``cdef`` function may be declared with an exception return value for it as a contract with the caller.
