How to use asynchronous I/O with your application

Points to remember include:

• The aiocb control block is the center of all asynchronous I/O requests. You must allocate a control block and assign values to its members before a call to aio_read or aio_write is made.

• Before an application exits or closes its file descriptors, it should ensure that all its Asynchronous I/O requests complete.

• If you want to lock an area of memory using aio_memlock, you must be sure that you are running the Kernel-based version of Asynchronous I/O.
