`numpy.ctypeslib:as_ctypes`

Signature

def as_ctypes ( obj )

Create and return a ctypes object from a numpy array. Actually anything that exposes the __array_interface__ is accepted.

Create ctypes object from inferred int ``np.array``:

inferred_int_array = np.array([1, 2, 3])
c_int_array = np.ctypeslib.as_ctypes(inferred_int_array)
type(c_int_array)
c_int_array[:]

Create ctypes object from explicit 8 bit unsigned int ``np.array`` :

exp_int_array = np.array([1, 2, 3], dtype=np.uint8)
c_int_array = np.ctypeslib.as_ctypes(exp_int_array)
type(c_int_array)
c_int_array[:]
