28.Sh DESCRIPTION
29The
30.Fn Pupdate_maps
31function is used to verify that all of the cached mappings in the
32process
33.Fa P
34are still valid and update the cached data with any new information.
35This is generally called in response to activity by the run-time
36link-editor.
37In general, the
38.Sy libproc
39library takes care of managing the need to call this function; however,
40debuggers, introspection tools, and others that are interposing on rtld
41activity or other actions, may need to call this function.
42Note that the
43.Fn Pupdate_maps
44function is only meaningful for active processes.
45It will do nothing on process handles that refer to core files, zombie
46processes, and ELF objects.
