VM_PAGE_WIRE(9) BSD Kernel Developer's Manual 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.
