This was removed because it is not +commonly needed and is not common practice with similar utilities. +.P +The functionality of +.IR mkfifo +is described substantially through a reference to the +\fImkfifo\fR() +function in the System Interfaces volume of POSIX.1\(hy2008. For example, by default, the mode of the FIFO +file is affected by the file mode creation mask in accordance with the +specified behavior of the +\fImkfifo\fR() +function.
