| .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. |
