.Sh DESCRIPTION
The
.Fn Plmid
function attempts to determine the link-map identifier that corresponds
to the address
.Fa addr
in the process
.Fa P .
If
.Fa addr
does not correspond to an address from an object mapped in by the
run-time link editor, such as anonymous mapping created with
.Xr mmap 2 ,
then there will be no corresponding link-map identifier.
.Pp
.Fa lmidp
must be a
.Pf non- Dv NULL
pointer that will be filled in with the link-map identifier when it is
successfully determined by the run-time link-editor.
.Sh RETURN VALUES
Upon successful completion, the
.Fn Plmid
function returns
.Sy 0
and updates
.Fa lmidp
with the link-map identifier of
.Fa addr .
Otherwise,
.Sy -1
is returned to indicate that the link-map identifier could not be
determined.
