class TPCANTimestamp (Structure):

    _fields_ = [ ("millis", c_uint),           # Base-value: milliseconds: 0.. 2^32-1

如何使用 TPCANTimestamp类中的字段？

将它们用作Structure的属性：

from ctypes import *


class TPCANTimestamp(Structure):
    """
    Represents a timestamp of a received PCAN message
    Total Microseconds = micros + 1000 * millis + 0x100000000 * 1000 * millis_overflow
    """
    _fields_ = [ ("millis", c_uint),           # Base-value: milliseconds: 0.. 2^32-1
                 ("millis_overflow", c_ushort), # Roll-arounds of millis
                 ("micros", c_ushort)]

t = TPCANTimestamp(100, 20, 30)
print(t.millis, t.micros)

输出：

100 30
