Today (Dec 10th) is the start of the format review of the Asynchronous
I/O library (asio) library by Christopher Kohlhoff. The review will run
until Friday December 23rd. I will be serving as review manager.

 From the library synopsis:

Boost.Asio is a cross-platform C++ library for network programming that
provides developers with a consistent asynchronous I/O model using a
modern C++ approach.

Downloads of the library as well as online documentation can be found at: (please refresh the page if you don't
see "Boost Review Material" at the top)

As usual, please state in review comments how you reviewed the library
and whether the you think the library should be accepted into Boost.
Further guidelines for writing reviews can be found on the website at:

Please review early and often!



A Few Library Details:
Supported Platforms

The following platforms and compilers have been tested:

    * Win32 using Visual C++ 7.1 and Visual C++ 8.0.
    * Win32 using Borland C++Builder 6 patch 4.
    * Win32 using MinGW.
    * Linux (2.4 or 2.6 kernels) using g++ 3.3 or later.
    * Solaris using g++ 3.3 or later.
    * Mac OS X 10.4 using g++ 3.3 or later.


The Boost.Asio library is intended for programmers using C++ for systems
programming, where access to operating system functionality such as
networking is often required. In particular, Boost.Asio attempts to
address the following goals:

    * Portability. The library should support, and provide consistent
behaviour across, a range of commonly used operating systems.
    * Scalability. The library should allow, and indeed encourage, the
development of network applications that scale to hundreds or thousands
of concurrent connections. The library implementation for each operating
system should use the mechanism that best enables this scalability.
    * Efficiency. The library should support techniques such as
scatter-gather I/O, and allow protocol implementations that minimise
data copying.
    * Model Berkeley sockets. The Berkeley sockets API is widely
implemented and understood, as well as being covered in much literature.
Other programming languages often use a similar interface for networking
    * Ease of use. Lower the entry barrier for new users by taking a
toolkit, rather than framework, approach. That is, try to minimise the
up-front investment in time to just learning a few basic rules and
guidelines. After that, a library user should only need to understand
the specific functions that are being used.
    * Basis for further abstraction. The library should permit the
development of other libraries that provide higher levels of
abstraction. For example, implementations of commonly used protocols
such as HTTP.

Although the current incarnation of Boost.Asio focuses primarily on
networking, its concepts of asynchronous I/O can be extended to include
other operating system resources such as files.
