Intel's C++ Asynchronous I/O Extensions for
Windows* Operating Systems
This topic only applies to Windows* OS.
Intel's C/C++ asynchronous input/output (Intel's C/C++ AIO) extensions, like library functions or classes, can be used to improve the performance of C/C++ applications by executing I/O operations in asynchronous mode. The extensions initiate I/O operation and immediately resume normal tasks while the I/O operations are executed in parallel.
Intel's C/C++ asynchronous I/O extensions are supported on IA-32 architecture- and Intel® 64 architecture-based Windows* platforms.
Intel's C/C++ AIO library functions and template class are implemented in the
libicaio.liblibrary. This library is supplied as part of the Intel® C/C++ Compiler package and is installed into the common directory:
Types of Intel's C/C++ Asynchronous I/O
Intel's C/C++ asynchronous I/O extensions comprise the following:
- Asynchronous I/O Library:A set of POSIX*-based asynchronous I/O library functions, supported on Windows* operating systems, for applications written in C/C++ language. The interface file isaio.h.
- Asynchronous I/O Template Class:Anasych_classtemplate class, supported on Windows* operating systems, for applications written in C++ language. This template class can be used to introduce asynchronous execution of I/O operations with the Standard Template Library's (STL's) streams classes. The interface file isaiostream.h.
