It's undocumented that cast() should work to directly convert Python strings to
pointers. Even when it seems to work, it's a risky thing to depend on because
there's no source ctypes data object to reference. Thus there's neither
_b_base_ nor anything in _objects
New submission from fooofei:
module:ctypes
pyversion: 2.7.13
python platform : win32, linux_x86_x64
I use ctypes.cast(v,ctypes.c_void_p).value to get address of 'helloworld' and
u'helloworld' internal buffer address.
the result is both right in win32,but not in linux.
'helloworld' is right,
