POLLHEAD_CLEAN(9F) Kernel Functions for Drivers POLLHEAD_CLEAN(9F)
pollhead_clean - inform the kernel that a pollhead is being
deallocated
#include <sys/poll.h>
void pollhead_clean(struct pollhead *php);
Architecture independent level 1 (DDI/DKI).
php
Pointer to a pollhead structure.
The pollhead_clean() function informs the kernel that a driver's
pollhead structure is about to be deallocated, usually as part of the
driver's close(9E) entry point before the software state that
contains the pollhead is deallocated via ddi_soft_state_free(9F).
See chpoll(9E), pollwakeup(9F) and poll(2) for more detail.
The pollhead_clean() function is generally called from the context of
a close(9E) entry point, but may be called from user or kernel
context.
