是Win32注册表“线程安全”？ [英] Is the Win32 Registry 'thread safe'?

问题描述

如果我有两个进程访问某个特定的注册表项（关HKLM的），它是一个好主意，包装在一个互斥逻辑？

If I have two processes accessing a given registry key (off of HKLM), is it a good idea to wrap the logic in a Mutex?

推荐答案

注册表将确保动作是原子的，所以你不必自己动手同步。

The registry will make sure the actions are atomic, so you don't have to synchronize it yourself.

不过，如果你有多个进程/线程访问注册表的同时，它不会使哪些首先发生任何保证。只有你不会得到乱码数据

However, if you have multiple processes / threads accessing the registry at the same time, it doesn't make any guarantees about which happens first. Only that you won't get garbled data.

编辑：进一步阅读，看的无力锁定有人出来注册表是一个特性，而不是bug 。
