NAME
	  mkfifo - Makes FIFO special files

     SYNOPSIS
	  mkfifo [-m mode] file	...


	  The mkfifo utility creates FIFO special files	in the order
	  specified.

     FLAGS
	  -m mode
	      Sets the file permission bits of the new file to the
	      specified	mode value, after creating the FIFO special
	      file.  The mode argument is a symbolic mode string (see
	      chmod), in which the operator characters + (plus sign)
	      and - (minus) are	interpreted relative to	the default
	      file mode	for that file type.  The + character adds per-
	      missions to the default mode, and	- deletes permissions
	      from the default mode.

	      The default mode is a=rw (permissions of rw-rw-rw).


     DESCRIPTION
	  For each file	argument, mkfifo performs actions equivalent
	  to the mkfifo() call with the	following arguments:


	   1.  The file	argument is used as the	pathname argument.

	   2.  The value of the	bitwise	inclusive OR of	S_IRUSR,
	       S_IWUSR,	S_IRGRP, S_IWGRP, S_IROTH, and S_IWOTH is used
	       as the mode argument.


     EXAMPLES
	   1.  To create a FIFO	special	file with permissions prw-r--
	       r--, enter:

	       mkfifo
	       -m 644 /tmp/myfifo

	       The command creates the /tmp/myfifo file	with
	       read/write permissions for the owner and	read permis-
	       sion for	the group and for others.

	   2.  To create a FIFO	special	file using the - (minus)
	       operand to set permissions of prw-r-----, enter:

	       mkfifo
	       -m g-w o-rw /tmp/fifo2
	       The command creates the /tmp/fifo2 file,	removing write
	       permission for the group	and all	permissions for	oth-
	       ers.


     EXIT VALUES
	  The mkfifo utility exits with	one of the following values:


	  0   Indicates	that all the specified FIFO special files were
	      created successfully.

	  >0  Indicates	that an	error occurred.
