Why not use ARP instead? there are a few portable utilities out there.. in C.
AFAIK,, arp table needs some time to update, so if a host comes online, its entry may not appear in the arp table instantly. Also, for the hosts isnt in the same subnet, the arp method doesnt work. ARP operates at layer 2, you know

For host detection purpose, I would choose nmap
