vm_page_wire(9)

NAME

vm_page_wire, vm_page_unwire - wire and unwire pages

SYNOPSIS

#include <sys/param.h>
#include <vm/vm.h>
#include <vm/vm_page.h>
void
vm_page_wire(vm_page_t m);
void
vm_page_unwire(vm_page_t m, int activate);

DESCRIPTION

The vm_page_wire() function increments the wire count on a

page, and
removes it from whatever queue it is on.

The vm_page_unwire() function releases one of the wirings on

the page.
When write_count reaches zero the page is placed back onto

either the
active queue (if activate is non-zero) or onto the inactive

queue (if
activate is zero). If the page is unmanaged (PG_UNMANAGED

is set) then
the page is left on PQ_NONE.
