What does pipe () return?

pipe() creates a pipe, a unidirectional data channel that can be used for interprocess communication. The array pipefd is used to return two file descriptors referring to the ends of the pipe. pipefd[0] refers to the read end of the pipe. pipefd[1] refers to the write end of the pipe.

What is named pipe in Linux?

A FIFO, also known as a named pipe, is a special file similar to a pipe but with a name on the filesystem.

Thus, the name works only as a reference point for processes that need to use a name in the filesystem.
