Win32注册表线程安全吗? [英] Is the Win32 registry thread-safe?

问题描述

如果我有两个进程访问给定的注册表项(例如HKLM)，我应该将逻辑包装在互斥锁中吗?

If I have two processes accessing a given registry key (e.g. HKLM), should I wrap the the logic in a mutex?

推荐答案

注册表将确保操作是原子的，因此您不必自己进行同步.

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

但是，如果您有多个进程/线程同时访问注册表，则不能保证先发生哪个事件.只是您不会得到乱码的数据.

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.
