Copy an empty file and ignore its empty contentFirst of all, what is called an empty file! For example, the following code:1#include 2#include string.h>3#include 4#include 5#include 6#include 7#include 8#include 9 Ten #defineMODE o_creat| o_rdwr|

The User Packet protocol ( User Datagram Protocal , UDP ) UDP requires only 1 sockets for both the server side and the client. TCPproviding services to 10 clients in, 10 server-side sockets are required in addition to the gatekeeper's server sockets.

Wrote two small programs, mainly for Linux and Windows under the TCP port detection, my own telnet can not meet the needs of my batch detection, in my eyes this type of port detection program is the most critical is the time-out limit, if the port

DescriptionThere are two ways to program Linux files:Linux system callsC Language Library functionsThe former relies on the Linux system, which is independent of the operating system.Under any operating system, the methods for manipulating files

Basic concepts of interprocess communicationinterprocess communication means that data can be exchanged between two different processes, but from the previous chapter we know that different processes are independent of each other, so to achieve

This paper gives a very useful small example of TCP communication between the server and the client. Concrete implementation is very simple, but usually write a similar program, the specific steps are often forgotten, but also always check, for the
