35.In vm/vm_map.h
36.Ft int
37.Fo vm_map_insert
38.Fa "vm_map_t map" "vm_object_t object" "vm_ooffset_t offset"

42.Sh DESCRIPTION
43The
44.Fn vm_map_insert
45function inserts a mapping for the entire vm_object
46.Fa object
47into the target map
48.Fa map .
49.Pp
50The
51.Fa offset
52argument specifies the offset into the
53.Fa object
54at which to begin mapping.
55The object's size should match that of the specified address range.
56.Pp
57The
58.Fa start
59and
60.Fa end
61arguments specify the bounds of the mapped object's window in the
62address space of
63.Fa map .
64.Pp
65The
66.Fa cow
67argument specifies the flags which should be propagated to the new entry,
68for example, to indicate that this is a copy-on-write mapping.
69.Sh IMPLEMENTATION NOTES
70This function implicitly creates a new
71.Vt vm_map_entry
72by calling the internal function
73.Fn vm_map_entry_create .
74.Sh RETURN VALUES
75The
76.Fn vm_map_insert
77function returns
78.Dv KERN_SUCCESS
79if the mapping could be made successfully.
80.Pp
81Otherwise,
82.Dv KERN_INVALID_ADDRESS
83will be returned if the start of the range could not be found, or
84.Dv KERN_NO_SPACE
85if the range was found to be part of an existing entry or if it
86overlaps the end of the map.
