The information of many common services (such as FTP and telnet) is listed in a text file. In/etc/services. The getservbyname () function

length of the message you want to send.L Flags send tokens. is generally set to 0. (You can view the man pages of Send to get additional parameter values and understand what each parameter means)l to is a pointer to a struct SOCKADDR structure that contains the IP address and port data of the remote host . L Tolen just indicates the size of the struct sockaddr in memory sizeof (struct sockaddr). like Send (), sendto () returns the number of bytes it really sends (as well as Send (), which is re

The IP address we usually use is a string of the type 192.168.1.11, and an IP address expressed in binary format in the Linux kernel. In programming, the conversion between IP addresses in string expression mode and binary IP addresses is often used. In network programming, there are a lot of address letters... The IP

I haven't read the Linux network programming book for a long time. Today I see the key part: TCP socket. Next let's take a look at the socket address Structure Linux sockets support multiple protocols. Each protocol uses a different address structure. In the header file

Article title: Linux Network Driver programming (4 ). Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. 3. notes for compiling

Linux under high concurrency Network programming 1, modify the user process can open the number of files limit on the Linux platform, regardless of writing the client program or server-side program, in the high-concurrency TCP connection processing, the highest concurrent number of the system to the user single process

UDP transmission. (2) The real-time application of the TCP protocol in the transmission process to carry out three handshake, retransmission confirmation and other means to ensure the reliability of data transmission. Using the TCP protocol will have a large delayWhen Therefore, it is not suitable for applications with high real-time. such as VoIP, video surveillance and so on. In contrast, the UDP protocol can play a very good role in these applications. (3)
