PMAP_UNWIRE(9)						   BSD Kernel Developer's Manual					    PMAP_UNWIRE(9)

NAME
     pmap_unwire -- unwire a range of virtual pages

SYNOPSIS
     #include <sys/param.h>
     #include <vm/vm.h>
     #include <vm/pmap.h>

     void
     pmap_unwire(pmap_t pmap, vm_offset_t start, vm_offset_t end);

DESCRIPTION
     The function pmap_unwire() removes the wired attribute from each of the virtual-to-physical page mappings within the virtual address range
     from start to end of the physical map pmap.  Every valid mapping within that range is required to have the wired attribute set.  Invalid map-
     pings are ignored, since they cannot have the wired attribute set.

NOTES
     Only the function pmap_enter(9) can be used to set the wired attribute of a virtual-to-physical page mapping.
