NAME

     mkfifo -- make fifos

SYNOPSIS

     mkfifo [-m mode] fifo_name ...

DESCRIPTION

     The mkfifo utility creates the fifos requested, in the order specified.

     The options are as follows:

     -m      Set the file permission bits of the created fifos to the specified mode, ignoring the umask(2) of the calling process.  The mode
	     argument takes any format that can be specified to the chmod(1) command.  If a symbolic mode is specified, the op symbols ``+''
	     (plus) and ``-'' (hyphen) are interpreted relative to an assumed initial mode of ``a=rw'' (read and write permissions for all).

     If the -m option is not specified, fifos are created with mode 0666 modified by the umask(2) of the calling process.  The mkfifo utility
     requires write permission in the parent directory.

DIAGNOSTICS

     The mkfifo utility exits 0 on success, and >0 if an error occurs.

STANDARDS

     The mkfifo utility is expected to be IEEE Std 1003.2 (``POSIX.2'') compliant.

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 creation 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 interpreted rela-
		tive 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_MES-
       SAGES, and NLSPATH.

EXIT STATUS

       The following exit values are returned:

       0	All the specified FIFO special files were created successfully.

       >0	An error occurred.
