>>> class Color(Structure): ... _fields_ = ( ... ('red', c_uint8), ... ('green', c_uint8), ... ('blue', c_uint8), ... ('intense', c_bool, 1), ... ('blinking', c_bool, 1), ... ) ... >>> Color.red <ctypes.CField 'red' type=c_ubyte, ofs=0, size=1> >>> Color.green.type <class 'ctypes.c_ubyte'> >>> Color.blue.byte_offset 2 >>> Color.intense <ctypes.CField 'intense' type=c_bool, ofs=3, bit_size=1, bit_offset=0> >>> Color.blinking.bit_offset 1
