getsockname() bad address error

[iemonslice]

I'm trying to retrieve the random port number the kernel assigned to my socket. Unfortunately getsockname() keeps throwing a bad address error and I have no idea why.... Hopefully someone can provide some assistance.

Below is the code segment:

    struct sockaddr_in target, me;
    int rc, sd;

    /* set target struct info*/
    target.sin_family = target_address->h_addrtype;
    memcpy((char *) &target.sin_addr.s_addr, 
            target_address->h_addr_list[0], target_address->h_length);
    target.sin_port = target_port;

    /* create socket */
    if ((sd = socket(AF_INET, SOCK_DGRAM, 0)) == -1){
        perror("socket");
	exit(1);
    }

    /* bind socket to random port */
    me.sin_family = AF_INET;
    me.sin_addr.s_addr = INADDR_ANY;
    me.sin_port = 0;
    if ((bind(sd, (struct sockaddr *) &me, sizeof(me))) == -1){
        perror("bind");
        exit(1);
    }

    /* connect UDP socket */
    if ((rc = connect(sd, (struct sockaddr *) &target, sizeof(target)))){
        perror("connect");
        exit(1);
    }

    /* get random port */
    if (getsockname(sd, (struct sockaddr *) &me, (int *)sizeof(me)) == -1){
        perror("getsockname");
	//exit(1);
    }
    printf("Listening on port %d\n", me.sin_port);

> (int *)sizeof(me)
This should be a pointer to a variable (of whatever type) containing the value sizeof(me)

socklen_t foo = sizeof(me);
getsockname(sd, (struct sockaddr *) &me, &foo )

Ah! much thanks.
