 .SH DESCRIPTION
-.LP
 The \fBepoll_wait()\fR function waits for events on the \fBepoll\fR(5)
 instance specified by \fIepfd\fR.  The \fIevents\fR parameter must point to
 an array of \fImaxevents\fR \fIepoll_event\fR structures to be
 filled in with pending events.  The \fItimeout\fR argument specifies the
 number of milliseconds to wait for an event if none is pending.  A

 .SH RETURN VALUES
-.LP
 Upon successful completion, \fBepoll_wait()\fR and \fBepoll_pwait()\fR return
 the number of events, or 0 if none was pending and \fItimeout\fR milliseconds
 elapsed.  If an error occurs, -1 is returned and errno is set to indicate
 the error.

 .SH NOTES
-.LP
-
 The \fBepoll\fR(5) facility is implemented for purposes of offering
 compatibility for Linux-borne applications; native
 applications should continue to prefer using event ports via the
 \fBport_create\fR(3C), \fBport_associate\fR(3C) and \fBport_get\fR(3C)
 interfaces.  See \fBepoll\fR(5) for compatibility details and restrictions.
