.TH mkfifo 1M "28 Jul 2011" "SunOS 5.11" "System Administration Commands"
.SH NAME
mkfifo \- make FIFO special file
.SH SYNOPSIS
.LP
.nf
\fB/usr/bin/mkfifo\fR [\fB-m\fR \fImode\fR] \fIpath\fR...
.fi

.SH DESCRIPTION
.sp
.LP
The \fBmkfifo\fR utility creates the \fBFIFO\fR special files named by its argument list. The arguments are taken sequentially, in the order specified; and each \fBFIFO\fR special file is either created completely or, in the case of an error or signal, not created at all.
.sp
.LP
If errors are encountered in creating one of the special files, \fBmkfifo\fR writes a diagnostic message to the standard error and continues with the remaining arguments, if any.
.sp
.LP
The \fBmkfifo\fR utility calls the library routine \fBmkfifo\fR(3C), with the \fIpath\fR argument is passed as the \fIpath\fR argument from the command line, and  \fImode\fR is set to the equivalent of \fBa=rw\fR, modified by the current value of the file mode creation mask \fBumask\fR(1).
.SH OPTIONS
.sp
.LP
The following option is supported:
.sp
.ne 2
.mk
.na
\fB\fB-m\fR \fImode\fR\fR
.ad
.RS 11n
.rt  
Set the file permission bits of the newly-created \fBFIFO\fR to the specified \fImode\fR value. The \fImode\fR option-argument will be the same as the \fImode\fR operand defined for the \fBchmod\fR(1) command. In <\fIsymbolic\fRmode> strings, the \fIop\fR characters \fB+\fR and \fB\(mi\fR will be interpreted relative to an assumed initial mode of \fBa=rw\fR.
