NAME
     mkfifo - make FIFOs

SYNOPSIS
     mkfifo [-m mode] fifo_name ...

DESCRIPTION
     mkfifo creates the FIFOs requested, in the order specified, using mode
     0666 modified by the current umask(2).

     The options are as follows:

     -m mode
             Set the file permission bits of newly created directories to
             mode. The mode is specified as in chmod(1). In symbolic mode
             strings, the ``+'' and ``-'' operators are interpreted relative
             to an assumed initial mode of ``a=rw''.

     mkfifo requires write permission in the parent directory.

     The mkfifo utility exits 0 on success or >0 if an error occurred.

     compliant.
