  .SH DESCRIPTION
- .LP
  The  \fB/dev/poll\fR driver is a special driver that enables you to monitor
  multiple sets  of polled file descriptors. By using the  \fB/dev/poll\fR
  driver, you can efficiently poll large numbers of file descriptors. Access to
  the \fB/dev/poll\fR driver is provided through \fBopen\fR(2), \fBwrite\fR(2),
  and  \fBioctl(2)\fR system calls.

  returned. The memory content pointed by \fBdp_fds\fR is not modified. A return
  value \fB0\fR means the ioctl is timed out. In this case, the memory content
  pointed by  \fBdp_fds\fR is not modified. If the call is successful, it returns
  the number of valid \fBpollfd\fR entries in  the array pointed by \fBdp_fds\fR;
  the contents of the rest of the buffer is undefined. For each valid
! \fBpollfd\fR entry, the \fBfd\fR field indicates the file desciptor on which
  the polled \fBevents\fR happened. The  \fBevents\fR field is the user specified
  \fBpoll\fR \fBevents\fR. The \fBrevents\fR field contains the  \fBevents\fR
  occurred. \fB-1\fR is returned if the  call fails.

  The \fBevents\fR field contains  \fB0\fR. The \fBrevents\fR field contains the
  currently polled \fBevents\fR. The ioctl returns  \fB0\fR if the file
  descriptor is not in the set. The  \fBpollfd\fR structure pointed by  \fIpfd\fR
  is not modified. The ioctl returns a  \fB-1\fR if the call fails.

  .SH NOTES
- .LP
  The \fB/dev/poll\fR API is particularly beneficial to applications that poll a
  large number of file descriptors repeatedly.  Applications will exhibit the
  best performance gain if the polled file descriptor list rarely change.
