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

Asio provides the basic building blocks for C++ networking, concurrency and other kinds of I/O. Asio is used in all kinds of applications, from phone apps to the world’s fastest share markets.

This is a build2 package for the standalone version of the Asio library.

Usage

This package provides the lib{asio} library.

SSL support is disabled by default. To enable it, add the following to your manifest:

depends:
\
libasio ^1.28.0
{
  require
  {
    config.libasio.ssl = true
  }
}
\

Note that on some platforms (such as MinGW) it may be necessary for applications to define _WIN32_WINNT to an appropriate value. If it's not defined the library's config.hpp header will issue a warning and choose a default (currently 0x0601, meaning Windows 7 and later; this is also the value that the library is built with).
