  • 0

I want my child process to send a signal to the parent process without destroying it. The only way I know to send a signal is to use kill(getppid(),SIGUSR1), however this is killing my parent process. How do I send a signal without killing it? I’m using a signal handler which runs but once it finishes, the parent process is killed. I would like to continue where I left off.

Thanks

    It is killing your parent process because you’re not installing a signal handler for SIGUSR1 in it.
