The \fBpollwakeup()\fR function wakes a process waiting on the occurrence of an event. It should be called from a driver for each occurrence of an event. The \fBpollhead\fR structure will usually be associated with the driver's private data structure associated with the particular minor device where the event has occurred. See \fBchpoll\fR(9E) and \fBpoll\fR(2) for more detail.
.SH CONTEXT

.LP
The \fBpollwakeup()\fR function can be called from user, interrupt, or kernel context.
