`mkfifo': Make FIFOs (named pipes)

   `mkfifo' creates FIFOs (also called "named pipes") with the
specified names.  Synopsis:

     mkfifo [OPTION] NAME...

   A "FIFO" is a special file type that permits independent processes
to communicate.  One process opens the FIFO file for writing, and
another for reading, after which data can flow as with the usual
anonymous pipe in shells or elsewhere.

   The program accepts the following option.  Also see Note: Common

`-m MODE'
     Set the mode of created FIFOs to MODE, which is symbolic as in
     `chmod' and uses `a=rw' (read and write allowed for everyone) minus
     the bits set in the umask for the point of departure.  Note: File
