NAME
pmap_is_modified, pmap_ts_modified -- return information about physical pages
SYNOPSIS
#include <sys/param.h> #include <vm/vm.h> #include <vm/pmap.h> boolean_t pmap_is_modified(vm_page_t m); int pmap_ts_referenced(vm_page_t m);
DESCRIPTION
The pmap_is_modified() and pmap_ts_referenced() functions return information about physical pages.
RETURN VALUES
The pmap_is_modified() function returns the status of the ``page modified'' bit for the physical page m. The pmap_ts_referenced() function returns a count of reference bits for a page m, clearing those bits. It is not necessary for every refer- ence bit to be cleared, but it is necessary that 0 only be returned when there are no remaining reference bits set on the page.
