Overview: Intel's C++ Asynchronous I/O Class

This topic only applies to Windows* OS.

Intel's C++ asynchronous I/O template class, async_class, is an implementation for the Windows* operating system on IA-32 and Intel® 64 architectures.

The async_class template class allows users to perform I/O operations asynchronously to the main program thread. In particular, the async_class template class can be used to introduce asynchronous execution of I/O operations with the STL streams classes. Users can quickly switch any of the I/O operations of the STL streams to asynchronous mode with minimal changes to the application code.

The template class async_class is defined in the aiostream.h file.
