+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl m
+Set the file permission bits of newly-created fifos to
+.Ar mode ,
+without respect to the current umask.
+.Pp
+The mode is specified as in 
+.Xr chmod 1 .
+In symbolic mode strings, the 
+.Dq + 
+and 
+.Dq -
+operators are interpreted relative to an assumed initial mode of 
+.Dq a=rw
+.El
+.Pp
+.Nm mkfifo
+requires write permission in the parent directory.
+.Pp
+.Nm mkfifo
+exits with 0 if successful, and with >0 if an error occurred.
+.Sh LEGACY DESCRIPTION
+In legacy mode, the fifo's file permission bits
+are always limited by the current umask.
+.Pp
+For more information about legacy mode, see
+.Xr compat 5 .
