Good, but ...

this code will fail rather horribly if sizeof(pid_t) != sizeof(int).
Even more to the point, I believe a standalone backend will put
the negative of its PID into the file, and the revised code will fail
to parse that at all.

I think the safest code would be like

	long	tmp;

	fscanf(pidf, "%ld", &tmp);
	if (tmp < 0)
	{
		tmp = -tmp;
		// do anything else needed for backend case
	}
	pid = (pid_t) tmp;
