Boost C++ Libraries: Ticket #5128: Implicit constant overflow in non_blocking_io::name()

(In [69194]) Changes for asio version 1.5.0:

Added support for timeouts on socket iostreams, such as ip::tcp::iostream. A timeout is set by calling expires_at() or expires_from_now() to establish a deadline. Any socket operations which occur past the deadline will put the iostream into a bad state.

Added a new error() member function to socket iostreams, for retrieving the error code from the most recent system call.

Added a new basic_deadline_timer::cancel_one() function. This function lets you cancel a single waiting handler on a timer. Handlers are cancelled in FIFO order.

Added a new transfer_exactly() completion condition. This can be used to send or receive a specified number of bytes even if the total size of the buffer (or buffer sequence) is larger.

Added new free functions connect() and async_connect(). These operations try each endpoint in a list until the socket is successfully connected.

Extended the buffer_size() function so that it works for buffer sequences in addition to individual buffers.

Added a new buffer_copy() function that can be used to copy the raw bytes between individual buffers and buffer sequences.

Added new non-throwing overloads of read(), read_at(), write() and write_at() that do not require a completion condition.

Added friendlier compiler errors for when a completion handler does not meet the necessary type requirements. When C++0x is available (currently supported for g++ 4.5 or later, and MSVC 10), static_assert is also used to generate an informative error message. Checking may be disabled by defining BOOST_ASIO_DISABLE_HANDLER_TYPE_REQUIREMENTS.

Made the is_loopback(), is_unspecified() and is_multicast() functions consistently available across the ip::address, ip::address_v4 and ip::address_v6 classes. Refs #3939.

Added new non_blocking() functions for managing the non-blocking behaviour of a socket or descriptor. The io_control() commands named non_blocking_io are now deprecated in favour of these new functions.

Added new native_non_blocking() functions for managing the non-blocking mode of the underlying socket or descriptor. These functions are intended to allow the encapsulation of arbitrary non-blocking system calls as asynchronous operations, in a way that is transparent to the user of the socket object. The functions have no effect on the behaviour of the synchronous operations of the socket or descriptor. Refs #3307.

Added the io_control() member function for socket acceptors. Refs #3297.

For consistency with the C++0x standard library, deprecated the native_type typedefs in favour of native_handle_type, and the native() member functions in favour of native_handle().

Added a release() member function to posix descriptors. This function releases ownership of the underlying native descriptor to the caller. Refs #3900.

Added support for sequenced packet sockets (SOCK_SEQPACKET).

Added a new io_service::stopped() function that can be used to determine whether the io_service has stopped (i.e. a reset() call is needed prior to any further calls to run(), run_one(), poll() or poll_one()).

Reduced the copying of handler function objects.

Added support for C++0x move construction to further reduce copying of handler objects. Move support is enabled when compiling in -std=c++0x mode on g++ 4.5 or higher, or when using MSVC10.

Removed the dependency on OS-provided macros for the well-known IPv4 and IPv6 addresses. This should eliminate the annoying "missing braces around initializer" warnings. Refs #3741.

Reduced the size of ip::basic_endpoint<> objects (such as ip::tcp::endpoint and ip::udp::endpoint).

Changed the reactor backends to assume that any descriptors or sockets added using assign() may have been dup()-ed, and so require explicit deregistration from the reactor. Refs #4971.

Changed the SSL error category to return error strings from the OpenSSL library.

Changed the separate compilation support such that, to use Asio's SSL capabilities, you should also include 'asio/ssl/impl/src.hpp in one source file in your program.

Removed the deprecated member functions named io_service(). The get_io_service() member functions should be used instead.

Removed the deprecated typedefs resolver_query and resolver_iterator from the ip::tcp, ip::udp and ip::icmp classes.

Fixed a compile error on some versions of g++ due to anonymous enums. Refs #4883.

Added an explicit cast to the FIONBIO constant to int to suppress a compiler warning on some platforms. Refs #5128.

Fixed warnings reported by g++'s -Wshadow compiler option. Refs #3905.
