Pointer: Pointer is an object in the programming language. Using the address, its value directly points to the value stored in another place in the computer memory. Because the required variable unit can be found through the address, and the address points to the variable unit, the address is visualized as "pointer", which means that ...

Port reuse is a classic problem in network programming, and the knowledge points in it are very cumbersome. This paper briefly introduces so through the code_ Reuseaddr, but so will not be involved_ REUSEPORT. For a long time, we all know that we can't listen to the same port. For example, the following code. server1.listen(8080); server2.li ...
