ctypes를 사용하여 Python과 DLL을 쉽게 인터페이스할 수 있는 방법은 무엇입니까?

<code class="python">import ctypes

# Load the DLL into memory
hllDll = ctypes.WinDLL("c:\PComm\ehlapi32.dll")

# Define the function prototype and parameters
hllApiProto = ctypes.WINFUNCTYPE(
ctypes.c_int,  # Return type
ctypes.c_void_p,  # Parameter 1
ctypes.c_void_p,
ctypes.c_void_p,
ctypes.c_void_p)  # ...

hllApiParams = (
(1, "p1", 0),
(1, "p2", 0),
(1, "p3", 0),
(1, "p4", 0))

# Create a Python-callable function
hllApi = hllApiProto(("HLLAPI", hllDll), hllApiParams)

# Call the DLL function with variables
p1 = ctypes.c_int(1)
p2 = ctypes.c_char_p(sessionVar)
p3 = ctypes.c_int(1)
p4 = ctypes.c_int(0)
hllApi(ctypes.byref(p1), p2, ctypes.byref(p3), ctypes.byref(p4))</code>
