Intro -- introduction to asynchronous I/O library routines

Description

The asynchronous input/output routines described in this section are defined in aio.h. They provide a user application with the ability to overlap CPU processing with I/O operations.

By default, asynchronous I/O is threads-based and supports all file types. You can also use a high performance, kernel-based implementation of Asynchronous I/O that supports only raw slices of hard disks.

You must link with libthread to use these routines.

Standards conformance

The asynchronous input/output functions conform to POSIX Part 1: System API Amendment 1 Realtime Extension (also known in draft form as POSIX P1003.4).
