如何检查文件是否被R / W锁定

Question

我已经查看了Python : Check file is locked和How to check whether a file is_open and the open_status in python。 通常，以下代码适合我的需要，但它在Python 2中不适用于Unicode字符串。

from ctypes import cdll

_sopen = cdll.msvcrt._sopen
_close = cdll.msvcrt._close
_SH_DENYRW = 0x10

def is_open(filename):
    h = _sopen(filename, 0, _SH_DENYRW, 0)
    try:
     return h == -1
    finally:
        _close(h)

有什么建议我应该做什么？

Answer 1

问题解决了！ 只需添加两行：

from ctypes import cdll

_sopen = cdll.msvcrt._sopen
_wsopen = cdll.msvcrt._wsopen
_close = cdll.msvcrt._close
_SH_DENYRW = 0x10

def is_open(filename):
    func = _wsopen if type(filename) is unicode else _sopen
    h = func(filename, 0, _SH_DENYRW, 0)
    try:
     return h == -1
    finally:
        _close(h)
