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

44.Sh DESCRIPTION
45The
46.Fn vm_map_insert
47function inserts a mapping for the entire vm_object
48.Fa object
49into the target map
50.Fa map .
51.Pp
52The
53.Fa offset
54argument specifies the offset into the
55.Fa object
56at which to begin mapping.
57The object's size should match that of the specified address range.
58.Pp
59The
60.Fa start
61and
62.Fa end
63arguments specify the bounds of the mapped object's window in the
64address space of
65.Fa map .
66.Pp
67The
68.Fa cow
69argument specifies the flags which should be propagated to the new entry,
70for example, to indicate that this is a copy-on-write mapping.
71.Sh IMPLEMENTATION NOTES
72This function implicitly creates a new
73.Vt vm_map_entry
74by calling the internal function
75.Fn vm_map_entry_create .
76.Sh RETURN VALUES
77The
78.Fn vm_map_insert
79function returns
80.Dv KERN_SUCCESS
81if the mapping could be made successfully.
82.Pp
83Otherwise,
84.Dv KERN_INVALID_ADDRESS
85will be returned if the start of the range could not be found, or
86.Dv KERN_NO_SPACE
87if the range was found to be part of an existing entry or if it
88overlaps the end of the map.
