Errata fixed through the seventh printing of C++NPv1

(Pages marked with '+' need a new page generated for next printing.)

. Page xxi: Added "Eric Eide," "Alexander Holler", "Craig Perras", "Bruce
  Trask", "Chris Uzdavinis", "Daire Lynch", and "Chris Smith" to list of
  contributors.
  Put "Luther Baker" and "Darrell Brunsch" in proper alphabetical order.
. Page 59: Default pathname (index.html) requires a leading '/' to work
  properly with most HTTP servers.
. Page 61 (in uml): ACE_SOCK_IO::recv() has an extra ',' after "ACE_Time_Value *"
. Page 61 (in UML): 4th arg to sendv_n() should be bytes_sent, not bytes_recvd.
. Page 62: Changed the phrase "where blocking I/O is the default" to 
  "With blocking I/O, the calling thread waits until the I/O completes."
. Page 63: returning "-1" from main() (should match convention on p. 67) 
  need to change "return peer.close ()" to "return peer.close () == -1 ? 1 : 0;" 
. Page 63: iov[1].iov_base = pathname caused the compiler to complain
  since pathname is const char* and iov_base is char*.  Fixed by
  adding (char *) casts. 
. Page 63: 3rd paragraph references the client_download_file()
  which doesn't exist.  The fix is to reference main() on this page.
. Page 64: TCP_NODELAY in  sidebar 6 should be set with 
  peer.set_option(), not with peer.enable().
. Page 64: Sidebar references client_download_file() which doesn't
  exist.  The fix is to reference main() on p. 63. 
. Page 67: peer->disable () should be peer.disable ().
. Page 67: The comment should be "Ensure blocking <send_n>" *not* "Ensure blocking <recv>s".
. Page 67: auto_ptr <char *> pathname = get_url_pathname (peer) 
  should be
  ACE_Auto_Array_Ptr <char> pathname (get_url_pathname (&peer))
. Page 75: If ACE::read_n() reports EOF after reading some bytes, the
  ACE_Message_Block wr_ptr() still needs to be advanced by the number of
  bytes actually read. Added an explicit nr_recvd argument to read_n()
  to receive this information.
. Page 76: ACE::write_n(head) should be ACE::write_n(ACE_STDOUT,head);
. Page 78: Transposed "typed" with "untyped" in 2nd paragraph. Output,
  not input, cdr classes xform typed data into untyped buffers.
. Page 81: Figure 4.4: "acceptor_ ; ACE_SOCK_Acceptor" should be
  "acceptor_ : ACE_SOCK_Acceptor". open() and wait() methods are virtual
  so should be italicized. w_short in open() should be u_short. In
  make_log_file, "s," should be "s :". Arrowheads on dashed lines should be
  open. Direction of association from Iterative Logging Server to
  Logging_Handler should be reversed, and arrowhead open.
. Page 82:  s/port/logger_port/ in open() method.
. Page 87: Logging_Handler (const ACE_SOCK_Stream&) can't initialize
  a reference (log_file_) with a 0. This isn't in the ACE_wrappers/examples
  code so is removed.
. Page 88: Example line 27 - need to add ACE_CDR::MAX_ALIGNMENT to be sure
  the revised size holds the header, payload, and any skipped align bytes.
  Also, use ACE_CDR::grow() to resize it, not ACE_Message_Block::resize(),
  in order to maintain CDR alignment.
. Page 92: s/port/logger_port/ in open() method.
. Page 96: On code line 7, "MAXLOGMSGLEN" should be
  "ACE_Log_Record::MAXLOGMSGLEN."
. Page 127: s/Set a handle to be/Mark a handle as/
. Page 144: Correctly check error return from select().
. Page 149: Changed "If n is a word, the expression n & ~(n - 1)
  accesses the least-significant bit (lsb) of n." to
  "If n is a word, the expression n &~(n - 1) computes a word in which
  the only set bit is the least-signficant set bit (lssb) of n."
  Also changed all subsequent occurrences of "lsb" to "lssb".
. Page 155: s/port/logger_port/
. Page 156: master_handle_set_.set_bit ( .. ) is called twice in
  handle_connections ().  Removed the first call.
  Added missing call to active_read_handles_.clr_bit in handle_connections().
. Page 160: Figure 8.1, the UML relationships are all wrong. There should be
  a one-to-many aggregation relationship from ACE_Process_Manager to
  ACE_Process and a dependency relationship from ACE_Process to
  ACE_Process_Options. There should be no relationship from ACE_Process_Manager
  to ACE_Process_Options.
. Page 163: Figure 8.2, the prepare(), spawn(), unmanage(), parent(), and
  child() methods are virtual and therefore should be italicized.
. Page 165: The code should start the first process off with n-1, not n.
  Also, when there's no environment variable, start n at 10, not 0.
. Page 167: Figure 8.3, setenv() method should be:
  + setenv (format : const char *, ...) : int
. Page 170: Figure 8.4, the two wait() methods should be:
  + wait (timeout : const ACE_Time_Value) : int
  + wait (pid : pid_t, timeout : const ACE_Time_Value,
          status : ACE_exitcode * = 0) : pid_t
. Page 172: Changed "where as" to "whereas".
. Page 176: In run_worker() method, ACE_static_cast should be
  ACE_reinterpret_cast.
. Page 178: Sidebar 18, item 3. The reference to Logging_Server::prepare()
  should be to Logging_Process::prepare().
. Page 178: Sidebar 18, item 4. The Logging_Process::prepare() method
  is on page 181, not page 180.
. Page 181: Changed "affect" to "effect"
. Page 187: Added a ``.'' after ``capabilities'' rather than a ``,''
  to avoid a ``comma splice."  Also added a ``.'' after ``mechanisms''
  rather than a ``,'' to avoid a ``comma splice.''
. Page 189: Figure 9.1 wait() method should show a second argument,
  abandon_detached_threads : int = 0.
. Page 191, replace "a ACE_SOCK_Stream" with "an ACE_SOCK_Stream"
. Page 193: Figure 9.2 should not have "Logging Acceptor" and "Reactor"
  boxes; should instead be one "Thread Per Connection Logging Server" box.
. Page 194,196: Use auto_ptr<> to manage allocated Thread_Args.
. Page 195: Figure in Sidebar 21, should not have spaces in
  ACE_Thread_Manager::spawn.
. Page 196: s/thread it's return/thread its return/
. Page 196: handle_data() parameter name is "client", not "logging_peer".
. Page 197: Thread_Per_Connection_Logging_Server reimplements run() to not call handle_data() - it's called in spawned threads.
. Page 197: Code example; call to ACE_Thread_Manager::wait() wants absolute
  time, not relative.
. Page 198: s/newly create thread/newly created thread/
. Page 199: in the box next to previous_priority: "If the priority is already the
  lower priority..."
  should be "If the priority is already the lowest priority..."
. Page 199: s/key methods outlined/key methods are outlined/
. Page 202: s/data is/data are/
. Page 210: Figure 10.2, ACE_Read-Guard should be ACE_Read_Guard.
. Page 215:
  Added the missing lines 
    logging_handler_.close ();
    return 0;
  to the end of handle_data() and removed a couple of blank lines so
  the page will still fit! 
. Page 233: Removed
  ACE_thread_t t_id = ACE_OS::thr_self ();
  and added 
  owner_id_ = 0;
. Page 248: s/not not/not/
. Page 254: The declaration of ACCEPTOR::PEER_ADDR addr does not need
  "typename" before it because ACCEPTOR is not a template argument.
. Page 287: The title of FJS99a should be "Implementing Application
  Frameworks: Object-Oriented Frameworks at Work"
. Page 287: The title of FJS99b should be "Building Application
  Frameworks: Object-Oriented Foundations of Framework Design"
