pipe

Pipe manager (QNX Neutrino)

You must be root to start this manager.

Syntax:

pipe

Options:

None.

Description:

The pipe manager implements the subset of file I/O known as pipes (or anonymous FIFOs). A simple form of interprocess communication, pipes are mostly used to connect the output of one process to the input of another to form a series of filters.

Examples:

Start the pipe manager:

    pipe &

Exit status:

The pipe utility terminates only if an error occurs during startup. If pipe fails during startup, it prints a diagnostic message to the standard output stream and then exits with a nonzero status.
