30.Sh DESCRIPTION
31The

40does not correspond to an address from an object mapped in by the
41run-time link editor, such as anonymous mapping created with
42.Xr mmap 2 ,
43then there will be no corresponding link-map identifier.
44.Pp
45.Fa lmidp
46must be a
47.Pf non- Dv NULL
48pointer that will be filled in with the link-map identifier when it is
49successfully determined by the run-time link-editor.

56.Fa lmidp
57with the link-map identifier of
58.Fa addr .
