linux network programming book

network programming in Linux is implemented through sockets (sockets).There are three types of sockets: Streaming sockets (SOCK_STREAM) streaming sockets can provide a reliable, connection-oriented traffic flow that uses the TCP protocol. TCP guarantees the correctness and sequencing of data transmission. Datagram Sockets (SOCK_DGRAM) datagram sockets define a no

Article title: Linux network programming-4. Complete read/write functions. 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. Once we estab

inaddr_any OptionsNetwork programming commonly used in the bind function, you need to bind the IP address, you can set Inaddr_any Inaddr_any is the specified address is 0. 0.0. 0 address, which in fact represents an indeterminate address, or "all addresses", "arbitrary addresses". That is to say that all the IP, because some of the machine more than one network card, multi-card case, this is the meaning o

2. Read the socket chapter of the linux/unix System Programming Manual, and call it a good book that surpasses apue. These chapters cover socket, select, poll, and epoll. Understanding the principles of select and poll, the advantages of epoll for high concurrency, the horizontal triggering and edge triggering of epoll Difference, how to solve the problem of ed

Eintr, just do their own on it.2. Use sleep to wait, the process will wake up when the signal occurs, after the socket wake up check if there is no processing signal (signal_pending) will return EINTR error.SoThe socket interface is not interrupted by a signal, just a call to sleep, a signal sleep is awakened to the notification process, and then the socket interface chooses to exit actively, so that you can avoid blocking there, there is an opportunity to exit. Sleep is not called when it is n

the subnet mask, Gateway is the next hop address, iface is the sending interface, and the U mark in flags indicates that the entry is valid (some entries can be disabled ), the G flag indicates that the next hop address of this route entry is the address of a vro, And the entry without the G flag indicates that the destination network address is a network directly connected to the local interface and does

The simple socket network programming instance in linux is provided here. The tcp protocol is used for communication. The server listens and sends data to the client after receiving the connection from the client; after receiving the data, the client prints the data and closes it. Detailed descriptions are provided in the program. For details about the implementa
