DESCRIPTION
The
vm_map_insert ();
function inserts a mapping for the entire vm_object
Fa object
into the target map
Fa map .
The
Fa offset
argument specifies the offset into the
Fa object
at which to begin mapping.
The object's size should match that of the specified address range.
The
Fa start
and
Fa end
arguments specify the bounds of the mapped object's window in the
address space of
Fa map .
The
Fa cow
argument specifies the flags which should be propagated to the new entry,
for example, to indicate that this is a copy-on-write mapping.
IMPLEMENTATION NOTES
This function implicitly creates a new
Vt vm_map_entry
by calling the internal function
vm_map_entry_create (.);
This function may use the
Giant
lock to ensure that only a single thread is present in the function.
RETURN VALUES
The
vm_map_insert ();
function returns
KERN_SUCCESS
if the mapping could be made successfully.
Otherwise,
KERN_INVALID_ADDRESS
will be returned if the start of the range could not be found, or
KERN_NO_SPACE
if the range was found to be part of an existing entry or if it
overlaps the end of the map.
