Preface

Due to the length, this article assumes that you are familiar with the basic principle of using Socket for TCP/IP programming, and have mastered the multi-thread programming technology, I will not mention the basic concept here, and the information on the Internet should be everywhere.

The full name of IOCP is the I/O Completion Port. IOCP is an asynchronous I/O Windows I/O model. It can automatically process I/O operations and send the completed notification to the user after the I/O operation is complete. This article describes IOCP-based network I/O operations (including socket Accept, Send, Recv, and Close ). Windows provides six network communication models:
