To the best of my knowledge only GNU/Linux and FreeBSD support prctl(PR_SET_PDEATHSIG) which is the kernel API for this. As far as I know this is not available on AIX. There are various ways that the child process could test whether it has been orphaned, but I don't know of any way to certainly kill the child. In Go, one approach you would use would be an os.Pipe in the parent. Have the child closing the writing end, and start a goroutine that reads from the reading end. If that read ever completes, the parent has died and the kernel has closed the descriptor. Ian -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
