To get to the point: recently Idle bored, remembered in second day when using VB to write a LAN multiplayer chat room. At that time using the Winsock, and then write out for the students to use information classes, in fact, there is no use AH . It was a whim this afternoon to implement this function in C + +. To Baidu a bit of relevant information, just found that C + + socket is really trouble ... ( Maybe

This article was reproduced from: http://www.cnblogs.com/youngforever/p/3250270.htmlThese two days to see the process of synchronization and communication, read a few books on the introduction, but also from the Internet search a lot of information, the more confused, the more puzzled by these issues are very tangled. What is the difference between process synchronization and mutex? What are the synchronization methods for a process?
