NAME    [Toc]    [Back]

     vm_map_clean -- push dirty pages to their pager

SYNOPSIS    [Toc]    [Back]

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

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

DESCRIPTION    [Toc]    [Back]

     The vm_map_clean() 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    [Toc]    [Back]

     The vm_map_clean() function returns KERN_SUCCESS if successful.  otherwise
 KERN_INVALID_ARGUMENT will be returned.

     Otherwise, KERN_INVALID_ADDRESS will be returned if the function encountered
 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.

IMPLEMENTATION NOTES    [Toc]    [Back]

     This routine holds the Giant lock to prevent multiple entry.
