.Sh DESCRIPTION
|
|
The
|
|
.Fn vm_map_insert
|
|
function inserts a mapping for the entire vm_object
|
|
.Fa object
|
|
into the target map
|
|
.Fa map .
|
|
.Pp
|
|
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.
|
|
.Pp
|
|
The
|
|
.Fa start
|
|
and
|
|
.Fa end
|
|
arguments specify the bounds of the mapped object's window in the
|
|
address space of
|
|
.Fa map .
|
|
.Pp
|
|
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.
|
|
.Sh IMPLEMENTATION NOTES
|
|
This function implicitly creates a new
|
|
.Vt vm_map_entry
|
|
by calling the internal function
|
|
.Fn vm_map_entry_create .
|
|
This function may use the
|
|
.Va Giant
|
|
lock to ensure that only a single thread is present in the function.
|
|
.Sh RETURN VALUES
|
|
The
|
|
.Fn vm_map_insert
|
|
function returns
|
|
.Dv KERN_SUCCESS
|
|
if the mapping could be made successfully.
|
|
.Pp
|
|
Otherwise,
|
|
.Dv KERN_INVALID_ADDRESS
|
|
will be returned if the start of the range could not be found, or
|
|
.Dv KERN_NO_SPACE
|
|
if the range was found to be part of an existing entry or if it
|
|
overlaps the end of the map.
