Named pipe

Common card · No. 449654

In computing, a named pipe (also known as a FIFO for its behavior) is an extension of the traditional pipe concept on Unix and Unix-like systems, and is one of the methods of inter-process communication (IPC). The concept is also found in the OS/2 and Microsoft Windows operating systems, although the programming semantics differ substantially. A traditional pipe is "unnamed" and lasts only as long as the process. A named pipe, on the other hand, can last as long as the system is up, beyond the life of the process, and can be deleted if no longer used. Usually a named pipe appears as a file, and generally processes attach to it for inter-process communication (IPC).
