/* test-getservbyname.c
 *
 * This basically tests the implementation of getservbyname to check
 * the ports being returned as it appeared that beos had a bug in it's
 * implementation. After testing it seems at though BeOS is correctly
 * returning the port network byte order.
 *
 *  gcc -Wall -g -O0 -o test-getservbyname test-getservbyname.c -lbind
 *
 * Test using
 *
 * ./test-getservbyname <service> <protocol>
 *
 * The protocol is optional and will default to tcp if not specified.
 *
 * This test illustrated the problem that we face. On OpenBSD 3.2 running 
 * this code gives 
 *
 * $ ./test-getservbyname ftp 
 * trying to get details for service ftp running over tcp...OK
 *                         hex    dec
 *   Port (as returned) : 0015     21
 *   Port (ntohs)       : 0015     21 
 *
 * On FreeBSD 4.9 we see
 *
 * $ ./test-getservbyname ftp 
 * trying to get details for service ftp running over tcp...OK
 *                         hex    dec
 *   Port (as returned) : 1500   5376
 *   Port (ntohs)       : 0015     21 
 * 
 * On BeOS BONE (7a) we get this
 *
 * $ ./test-getservbyname ftp 
 * trying to get details for service ftp running over tcp...OK
 *                         hex    dec
 *   Port (as returned) : 1500   5376
 *   Port (ntohs)       : 0015     21
