TerminateProcess和死锁 [英] TerminateProcess and deadlocks

问题描述

是否真的Windows中的TerminateProcess函数可能挂起，因为进程内的线程陷入了死锁？

Is it real that the TerminateProcess function in Windows could hang because the threads inside the process were stuck in a deadlock?

示例：进程A正在运行进程B控制，现在进程A进入死锁，进程B检测到并决定使用TerminateProcess终止进程A.

Example: Process A is running under Process B's control, now Process A gets into a deadlock and Process B detects this and decides to 'Kill' process A using TerminateProcess.

能否成功杀死已暂停的进程A？

Would it be successful in killing the hung Process A?

推荐答案

是的，进程持有的所有内核对象都将被释放，包括锁。

Yes, all kernel objects held by the process will be released, including locks.

TerminateProcess的主要问题是进程在事情上没有发言权：if it's保持任何全局状态（文件，共享内存等），那么你不能保证这些事情在进程终止后处于一致状态。

The main problem with TerminateProcess is that the process has no say in the matter: if it's holding on to any global state (files, shared memory, etc) then you have no guarantee those things are in a consistent state after the process is terminated.
