Thread: Checking if a process has terminated?

No, I explicitly test this by starting a child process that does nothing but sleep, and then killing it with kill.

Code:

#ifdef SIGNALDETECTION
void child_status_change_handler(int signum)
{
	puts("Signal recieved!");
	signum = signum; // Eliminate unused warning
	check_for_terminated_processes();
}
#endif

int main()
{
	char buf[2048];

	signal(SIGCHLD, &child_status_change_handler);

	for (;;)
	{
		sighold(SIGCHLD);
		printf("Ready>");
		fgets(buf, sizeof(buf), stdin);
		sigrelse(SIGCHLD);

		const char* cmd;
		const char* arg[5];
		timeval begin;

		sighold(SIGCHLD);
		if (!get_command_and_args(buf, &cmd, arg)) goto Error;
		bool failure = (!handle_command(cmd, arg, &begin));
		sigrelse(SIGCHLD);
	}
}

I'll start with this. This is not the complete code, but a mini-version of it to provide an overview.
I may include check_for_terminated_processes later if deemed necessary.
