1, pipeline overview and related API application1.1 Key concepts related to pipingThe pipeline is one of the original UNIX IPC forms supported by Linux and has the following features: The pipe is half-duplex, the data can only flow in one

Piping ConceptsPipelines are the oldest form of interprocess communication in Unix, and we refer to a data flow from one process to another as a "pipe", the essence of which is a fixed-size kernel buffer ;such as: PS aux | grep httpd | awk ' {print $

13. Nameless Pipe Communication programming?1. Inter-process communication:Linux, as a typical multi-process operating system, requires the communication of information between processes and processes, which requires process communications.2.
