73 The \fB/dev/poll\fR driver is a special driver that enables you to monitor
74 multiple sets of polled file descriptors. By using the \fB/dev/poll\fR
75 driver, you can efficiently poll large numbers of file descriptors. Access to
76 the \fB/dev/poll\fR driver is provided through \fBopen\fR(2), \fBwrite\fR(2),
