Input/output completion port
http://dbpedia.org/resource/Input/output_completion_port an entity of type: Software
Input/output completion port (IOCP) is an API for performing multiple simultaneous asynchronous input/output operations in Windows NT versions 3.5 and later, AIX and on Solaris 10 and later. An input/output completion port object is created and associated with a number of sockets or file handles. When I/O services are requested on the object, completion is indicated by a message queued to the I/O completion port. A process requesting I/O services is not notified of completion of the I/O services, but instead checks the I/O completion port's message queue to determine the status of its I/O requests. The I/O completion port manages multiple threads and their concurrency.

输入输出完成端口（Input/Output Completion Port，IOCP）, 是支持多个同时发生的异步I/O操作的应用程序编程接口，在Windows NT的3.5版本以後，或AIX 5版以後或Solaris第十版以後，開始支持。 IOCP特别适合C/S模式网络服务器端模型。因为，让每一个socket有一个线程负责同步（阻塞）数据处理，one-thread-per-client的缺点是：一是如果连入的客户多了，就需要同样多的线程；二是不同的socket的数据处理都要线程切换的代价。
