loopback sample problem

[Grigori Khmyrov]

Thanks everybody for pointing me to the right direction.
I found the errors in the loopback's source code.
There is result of comparing files init.c and INIT_ORIG.C

init.c is fixed one, INIT_ORIG.C is original one from the distribution
rtems-4.6.2/c/src/tests/samples/loopback/

May be somebody can submit  changes to the  new RTEMS distribution
because it scare when even simple examples don't work.

1. Strange printf parameters.
***** init.c
    printf("Read %d from server: %s\n", i, cbuf);
***** INIT_ORIG.C
    printf("Read %d from server: %.*s\n", i, i, cbuf);
*****
2. Delete task after client done
***** init.c
    printf("Client task terminating.\n");
    rtems_task_delete(RTEMS_SELF);
}
***** INIT_ORIG.C
    printf("Client task terminating.\n");
}
*****
Let some time to server to run (Server has low priority compare to client)
***** init.c
    spawnTask(serverTask, 150, 0);
    rtems_task_wake_after(20); /* Simulate client delay */

***** INIT_ORIG.C
    spawnTask(serverTask, 150, 0);

*****

Let's make RTEMS better!!!
