|
|
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).
