捕获正在运行的进程关闭的 Windows 终端 [英] Catch Windows terminal closing on running process

问题描述

在命令提示符窗口中，我有一个正在运行的进程.当进程仍在执行时，我单击命令提示符窗口角落中的(红色)X".命令提示符窗口关闭，正在运行的进程终止.

In a command prompt window, I have a running process. While the process is still executing, I click the (red) 'X' in the corner of the command prompt window. The command prompt window closes, and the running process is terminated.

在 Linux 上，关闭正在运行的进程的父终端将发送该进程 SIGHUP.如何在 Windows 上捕获此事件?

On Linux, closing the parent terminal of a running process will send that process SIGHUP. How do I catch this event on Windows?

推荐答案

SIGHUP 的等效项是通过您在 SetConsoleCtrlHandler.您的回调函数将在任意线程池线程上使用 dwCtrlType = CTRL_CLOSE_EVENT 调用.您有 5 秒的时间清理，您无法取消关闭.

The equivalent of SIGHUP is provided through the callback you register with SetConsoleCtrlHandler. Your callback function will be called on an arbitrary threadpool thread with dwCtrlType = CTRL_CLOSE_EVENT. You've got 5 seconds to clean-up, you cannot cancel the close.
