| .Sh DESCRIPTION |
| The |
| .Fn Pupdate_maps |
| function is used to verify that all of the cached mappings in the |
| process |
| .Fa P |
| are still valid and update the cached data with any new information. |
| This is generally called in response to activity by the run-time |
| link-editor. |
| In general, the |
| .Sy libproc |
| library takes care of managing the need to call this function; however, |
| debuggers, introspection tools, and others that are interposing on rtld |
| activity or other actions, may need to call this function. |
| Note that the |
| .Fn Pupdate_maps |
| function is only meaningful for active processes. |
| It will do nothing on process handles that refer to core files, zombie |
| processes, and ELF objects. |
