 12.4 ‘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 options.  Also see ⇒Common
 options.
 
 ‘-m MODE’
 ‘--mode=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) for
      the point of departure.  MODE should specify only file permission
      bits.  ⇒File permissions.
 
 ‘-Z’
 ‘--context[=CONTEXT]’
      Without a specified CONTEXT, adjust the SELinux security context
      according to the system default type for destination files,
      similarly to the ‘restorecon’ command.  The long form of this
      option with a specific context specified, will set the context for
      newly created files only.  With a specified context, if both
      SELinux and SMACK are disabled, a warning is issued.
 
    An exit status of zero indicates success, and a nonzero value
 indicates failure.
