导读：Linux asynchronous I/O is a relatively recent addition to the Linux kernel. It's a standard feature of the 2.6 kernel,but you can find patches for 2.4. The basic idea behind AIO is to allow a process to initiate a number of I/O operations
The primary issue with the?select?call is that it's not very efficient. While it's a convenient model for asynchronous notification,its use for high-performance I/O is not advised.
