there is an IPython magic for CFFI: https://github.com/Carreau/cffi_magic

https://tmarkovich.github.io//articles/2017-08/linking-python-to-c-with-cffi

these are just some random experiments ...

from cffi import FFI
ffi = FFI()

In [ ]:

ffi.cdef("""
typedef void mytype;
""")

In [ ]:

ptrptr = ffi.new("mytype**")
ptrptr

In [ ]:

type(ptrptr)

In [ ]:

ptrptr[0]

In [ ]:

ptrptr[0] += 1
ptrptr[0]

In [ ]:

ptr = ptrptr[0]
ptr

In [ ]:

type(ptr)

ptr is a separate, non-owning cdata object. It is not pointing to the original data.

In [ ]:

ptr += 1
ptr

In [ ]:

ptrptr[0]

In [ ]:

del ptrptr

In [ ]:

ptr
