Re: How to automatically kill all children threads when the main thread die

Yes, there is task group concept and support by kill API directly: https://pubs.opengroup.org/onlinepubs/009604499/functions/kill.html If *pid* is negative, but not -1, *sig* shall be sent to all processes (excluding an unspecified set of system processes) whose process group ID is equal to the ab

Re: How to automatically kill all children threads when the main thread die

If you kill a process in Linux. All of its child processes should continue to run as orphan processes. This is the Linux compatible behavior for the case that Alan presented. On Sun, Jan 15, 2023 at 10:31 PM Gregory Nutt wrote: > That wouldn’t be consistent with how Linux works, would it? I'm

RE: How to automatically kill all children threads when the main thread die

That wouldn’t be consistent with how Linux works, would it? I'm not an expert on this topic and I am sure that other people on this list know more about this than me. My understanding is that Linux has "session leaders" which correspond to login sessions. For each terminal opened by the session

Re: How to automatically kill all children threads when the main thread die

If CONFIG_SIG_DEFAULT, the kernel will terminate all child pthreads, but not child tasks. We can extend kill to support -P flag like pkill: https://linux.die.net/man/1/pkill -P ppid,... Only match processes whose parent process ID is listed. On Mon, Jan 16, 2023 at 10:14 AM Gregory Nutt wrote: >

Re: How to automatically kill all children threads when the main thread die

Ooops. No, you a re asking about tasks, not threads. That is easier. The answer is no: One task exiting has not effect at all any other tasks. In Linux, you can use the kill command to signal an entire process group, but that the last time I looked, there was no support for process groups in N

Re: How to automatically kill all children threads when the main thread die

Xaio Xiang problem will know the current behavior better then me, But I think you need: only pthread support. See use of HAVE_GROUP_MEMERS in sched/task/exit.c. see include/nuttx/sched.h for definition of HAVE_GROUP_MEMBERS. (seems to depend only on phtreads). On Sun, Jan 15, 2023 at 5:25 PM A
