P110 solves three scenarios that network programming may encounter: (1) When fork a child process, the SIGCHLD signal must be captured; (Understanding: The capture here is not immediately captured, but is registered to capture the signal and is captured whenever the child process sends a signal.) Why to register early is because you do not know when the child pro

Chapter II Transport layer: TCP and UDP User Packet Protocol UDP The problem with UDP for network programming is the lack of reliability, and we also call it a non-connected (connectionless) service because UDP customers and server do not have to have a long-term relationship. Transmission Control Protocol TCP TCP provides a client-to-server connection. A TCP client establishes a connection to a given
