Eryk Sun added the comment: You can send CTRL_C_EVENT to a process group. But it requires the group leader to manually enable Ctrl+C handling. Initially it's disabled when creating a process with CREATE_NEW_PROCESS_GROUP.
The attached script demonstrates sending CTRL_C_EVENT to a process group. The child process is the group leader, so CTRL+C event processing has to be manually enabled in it by calling SetConsoleCtrlHandler(NULL, FALSE). This flag gets inherited by the grandchild process. Example output: Process 0300: created process 0464 Process 0464: created process 0456 Process 0464: received CTRL+C Process 0456: received CTRL+C That said, given that MSDN [erroneously] claims that this isn't possible, probably the subprocess docs should only mention sending CTRL_BREAK_EVENT. ---------- nosy: +eryksun versions: +Python 3.4, Python 3.5, Python 3.6 -Python 3.2, Python 3.3 Added file: http://bugs.python.org/file41242/proc_group_ctrl_c.py _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue13368> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
