Problem with emulating socketpair(2)

[Tim Ramsey]

I'm trying to write a function that will connect two sockets together.
This piece of code creates a socket, returning its file descriptor:

struct in_addr	host_addr;  /* Initialized to 0's */

makesock()
{
	int	sock;
	struct sockaddr_in	name;

	if ((sock = socket(AF_INET, SOCK_STREAM, 0)) == -1) {
		perror("socket");
		exit(1);
	}
	name.sin_addr = host_addr;
	name.sin_port = 0;
	if (bind(sock, &name, sizeof (name)) == -1) {
		perror("bind");
		exit(1);
	}
	return (sock);
}


This piece of code is *supposed* to connect the two sockets created by
makesock() together:

attach(one, two)
int	one, two;
{
	struct sockaddr_in	name;
	int	length;

	length = sizeof (name);
	if (getsockname(one, &name, &length) == -1) {
		perror("getsockname one");
		exit(1);
	}
	if (connect(two, &name, length) == -1) {
		perror("connect two");
		exit(1);
	}
	[ reverse one and two, repeat ]
}

The connect fails with the error EADDRNOTAVAIL ("Can't assign requested
address").  What am I doing wrong?

Disclaimer: I'm not using socketpair(2) because this implementation forgot
to include it, even though it's listed in the manual.  I'm using SysV
Rel2.1.2 with WIN/3B TCP/IP 1.1.

Thanks for any help or pointers you can provide.
