mkfifo -- make fifos SYNOPSIS
mkfifo [-m mode] fifo_name ... DESCRIPTION
mkfifo creates the fifos requested, in the order specified, using mode 0666 modified by the current umask(2). The options are as follows: -m Set the file permission bits of newly-created fifos to mode. The mode is specified as in chmod(1). In symbolic mode strings, the ``+'' and ``-'' operators are interpreted relative to an assumed initial mode of ``a=rw'' mkfifo requires write permission in the parent directory. mkfifo exits 0 if successful, and >0 if an error occurred. SEE ALSO
mkdir(1), rm(1), mkfifo(2), mknod(8) STANDARDS

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 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_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. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWesu | +-----------------------------+-----------------------------+ |Interface Stability |Standard | +-----------------------------+-----------------------------+ SEE ALSO
