I would not call it obvious, but you can do
>>> m = memoryview(bytearray(5))
>>> ctypes.addressof(ctypes.c_char.from_buffer(m))
149979304
However, this only works for writable memoryviews. For
read-only memoryviews you could do
>>> obj = ctypes.py_object(m)
>>> address = ctypes.c_void_p()
>>> length = ctypes.c_ssize_t()
>>> ctypes.pythonapi.PyObject_AsReadBuffer(obj,
ctypes.byref(address), ctypes.byref(length))
0
>>> address, length
(c_void_p(149979304), c_long(5))
