Boost
C++ Libraries
...one of the most highly
regarded and expertly designed C++ library projects in the
world.
— Herb Sutter and Andrei
Alexandrescu, C++
Coding Standards
This is an older version of Boost and was released in 2018. The current version is 1.89.0.
When supported by a compiler, Boost.Asio can use variadic templates to implement the basic_socket_streambuf::connect() and basic_socket_iostream::connect() functions.
Support for variadic templates is automatically enabled for g++
4.3 and later, when the -std=c++0x or -std=gnu++0x
compiler options are used. It may be disabled by defining BOOST_ASIO_DISABLE_VARIADIC_TEMPLATES,
or explicitly enabled for other compilers by defining BOOST_ASIO_HAS_VARIADIC_TEMPLATES.
