#include <sys/poll.h>void pollwakeup(struct pollhead *php, short event);
Architecture independent level 1 (DDI/DKI).
pollwakeup() wakes a process waiting on the occurrence of an event. It should be called from a driver for each occurrence of an event. The pollhead structure will usually be associated with the driver's private data structure associated with the particular minor device where the event has occurred. See chpoll(9E) and poll(2) for more detail.
pollwakeup() can be called from user or interrupt context.
Driver defined locks should not be held across calls to this function.
