If you're on a 4.x BSD machine, or another one that has the `inet'
library, the accepted way to parse Internet addresses is:

----------------------------------------
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>

...

	char * address_in_dotted_form;
	unsigned long parsed_address;

...

	parsed_address = inet_addr (address_in_dotted_form);
----------------------------------------

The manual page for this is inet(3n).
