int
vm_map_sync
(vm_map_t map,
vm_offset_t start, vm_offset_t
end, boolean_t syncio, boolean_t
invalidate);
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.
The vm_map_sync
() function returns
KERN_SUCCESS
if successful.
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.
