DESCRIPTION

27       The  pollwakeup() function wakes a process waiting on the occurrence of
28       an event. It should be called from a driver for each occurrence  of  an
29       event.  The  pollhead  structure  will  usually  be associated with the
30       driver's private data structure associated with  the  particular  minor
31       device  where  the  event  has occurred. See chpoll(9E) and poll(2) for
32       more detail.
33

CONTEXT

36       context.
