/* test-getaddrinfo.c
 *
 * Test to make sure that getaddrinfo works as expected.
 *
 * gcc -Wall -g -O0 -o test-getaddrinfo test-getaddrinfo.c -lbind
 *
 * Usage is ./test-getaddrinfo <host> <port>
 *
 * This shows that getaddrinfo on BeOS BONE is broken (on BONE 7a)
 * as shown below. (getnameinfo is also broken).
 *
 * FreeBSD 4.9 (20480 is decimal for 80 in network byte order)
 *
 *  $ ./test-getaddrinfo www.google.com 80
 * managed to get details for host www.google.com, port 80
 * Checking returned hosts using getnameinfo:
 *   1: sockaddr    : 66.102.9.104 port 20480 =>  OK
 *      getnameinfo : 66.102.9.104 port '80'
 *   2: sockaddr    : 66.102.9.99 port 20480 =>  OK
 *      getnameinfo : 66.102.9.99 port '80' 
 *
 * BeOS BONE 7a
 *
 *  $ ./test-getaddrinfo www.google.com 80
 * managed to get details for host www.google.com, port 80
 * Checking returned hosts using getnameinfo:

 *   2: sockaddr    : 66.102.9.99 port 80 =>  OK
