mkfifo


NAME
     mkfifo - make FIFO special file

SYNOPSIS
     /usr/bin/mkfifo [-m mode] path...

DESCRIPTION
     The mkfifo utility creates the FIFO special files  named  by
     its  argument list. The arguments are taken sequentially, in
     the order specified; and each FIFO special  file  is  either
     created  completely  or,  in the case of an error or signal,
     not created at all.

     If errors are encountered in creating  one  of  the  special
     files,  mkfifo  writes  a diagnostic message to the standard
     error and continues with the remaining arguments, if any.

     The mkfifo utility calls  the  library  routine  mkfifo(3C),
     with  the  path argument is passed as the path argument from
     the command line, and  mode is  set  to  the  equivalent  of
     a=rw,  modified  by the current value of the file mode crea-
     tion mask umask(1).

OPTIONS
     The following option is supported:

     -m mode  Sets the file permission bits of the  newly-created
              FIFO  to the specified mode value. The mode option-
              argument will be  the  same  as  the  mode  operand
              defined for the chmod(1) command. In <symbolicmode>
              strings, the op characters + and - will  be  inter-
              preted relative to an assumed initial mode of a=rw.



OPERANDS
     The following operand is supported:

     file     A path name of the FIFO special file to be created.



USAGE
     See largefile(5) for the  description  of  the  behavior  of
     mkfifo  when  encountering  files greater than or equal to 2
     Gbyte ( 2**31 bytes).

ENVIRONMENT VARIABLES
     See environ(5) for descriptions of the following environment
     variables that affect the execution of mkfifo: LANG, LC_ALL,
     LC_CTYPE, LC_MESSAGES, and NLSPATH.

EXIT STATUS
     The following exit values are returned:

     0        All the specified FIFO special files  were  created
              successfully.



     >0       An error occurred.
