sizeof function in cffi doesn't work in pypy
The sizeof function doesn't return the correct size of an array in pypy. But it works well in cpython.
from cffi import FFI from array import array N = 2**20 x = array('i') for i in range(N): x.append(i) ffi = FFI() y = ffi.from_buffer('int ', x) print('the size of y equal 4*N', ffi.sizeof(y) == N * 4)
