Hi. In my application I do something very simple - I open a file, lock
it exclusively, write some data to it and close it.

否。一方面它是私有的商业代码，第二，我已经给出了足够的关于这个问题的信息。
我不会很感激人们做出类似的讽刺评论。如果你不知道问题然后保持安静，或者如果你真的没有重要的细节，请提出礼貌请求，例如： 你是否在关闭和重新打开文件之间做了X
。对于你的不安全和自我问题，我不是一个出口
。
如果你真的那么缺乏想象力，那么这里有一些代码（使用我的
将原始描述作为设计规范，证明了我的观点：
define（FILE_NAME，" somefile.txt"）;
No. For one thing it''s private, commercial code, and secondly, I''ve
given enough information about the problem.
I don''t appreciate people making sarcastic comments like that. If you
have no idea about the problem then keep quiet, or if you genuinely
are missing important details, make a polite request, e.g. "Are you
doing X between closing and re-opening the file?". I''m not an outlet
for problems with your insecurities and ego.
If you really are that unimaginative, then here''s some code (using my
own original description as a design spec, proving my point somewhat):
define(FILE_NAME, "somefile.txt");
dataOrig = array（" here，is，some，data，to，be） ，
" serialized"）;
dataOrig = array("here", "is", "some", "data", "to", "be",
"serialized");
