NAME
     vm_map_sync -- push dirty pages to	their pager

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

     int
     vm_map_sync(vm_map_t map, vm_offset_t start, vm_offset_t end,
	 boolean_t syncio, boolean_t invalidate);

DESCRIPTION
     The vm_map_sync() function	forces any dirty cached	pages in the range
     start to end within the map to be pushed to their underlying pager.

     If	syncio is TRUE,	dirty pages are	written	synchronously.

     If	invalidate is TRUE, any	cached pages are also freed.

     The range provided	must be	contiguous, it MUST NOT	contain	holes.	The
     range provided MUST NOT contain any sub-map entries.

RETURN VALUES
     The vm_map_sync() function	returns	KERN_SUCCESS if	successful.

     Otherwise,	KERN_INVALID_ADDRESS will be returned if the function encoun-
     tered a sub-map entry; KERN_INVALID_ARGUMENT will be returned if the
     function encountered a hole in the	region provided, or if an entry	could
     not be found for the given	start address.
