I'm using this


>>import ctypes
hllDll=ctypes.WinDLL("C:\\AS5216.dll")


hllApiProto = ctypes.WINFUNCTYPE (ctypes.c_int,ctypes.c_void_p,
    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),


hllApi = hllApiProto (("HLLAPI", hllDll), hllApiParams)

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))



Thanks
