More complete example
---------------------
-.. note:: This example depends on pypy_execute_source_ptr which is not
available
- in PyPy <= 2.2.1.
+.. note:: Note that we do not make use of ``extern "Python"``, the new
+ way to do callbacks in CFFI 1.4: this is because these examples use
+ the ABI mode, not the API mode, and with the ABI mode you still have
+ to use ``ffi.callback()``. It is work in progress to integrate
+ ``extern "Python"`` with the idea of embedding (and it is expected
+ to ultimately lead to a better way to do embedding than the one
+ described here, and that would work equally well on CPython and PyPy).
Typically we need something more to do than simply execute source. The
following
is a fully fledged example, please consult cffi documentation for details.
