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 Fa activate is non-zero) or onto the inactive queue (if Fa activate is zero). If the page is unmanaged ( PG_UNMANAGED is set) then the page is left on PQ_NONE
