"Activating swap" usually means enabling swap by pointing the kernel to a swap partition or file to swap on, and that's what the swapon(2) system call is used for. What you probably mean is called "swapping out". Figuring out which pages can be swapped out is quite a hairy subject and whatever algorithm you come up with, there will always be a corner case where it will fail.
