Name: UNIX::MKFIFO

Section: File Operators

Synopsis:

<unix::mkfifo FILENAME &optional [MODE-BITS]

Description:

Create a named pipe on unix systems that support named pipes.

The pipe is named FILENAME and is created with the access mode specified by MODE-BITS, an octal permissions mask.

MODE-BITS defaults to 0666 if not specified.

After a named pipe is created, it can be written to and read from in the normal manner for writing and reading file streams.

UNIX::MKFIFO returns "true" if the named pipe could be created, or the empty string if not. In the case of an error, the human readable text of the error message appears in SYSTEM-ERROR-OUTPUT.
