17.Sh NAME
18.Nm Pupdate_maps
19.Nd update address space mappings
20.Sh SYNOPSIS
21.Lb libproc
22.In libproc.h
23.Ft void
24.Fo Pupdate_maps
25.Fa "struct ps_prochandle *P"
26.Fc
27.Sh DESCRIPTION
28The
29.Fn Pupdate_maps
30function is used to verify that all of the cached mappings in the
31process
32.Fa P
33are still valid and update the cached data with any new information.
34This is generally called in response to activity by the run-time
35link-editor.
36In general, the
37.Sy libproc
38library takes care of managing the need to call this function; however,
39debuggers, introspection tools, and others that are interposing on rtld
40activity or other actions, may need to call this function.
41Note that the
42.Fn Pupdate_maps
43function is only meaningful for active processes.
44It will do nothing on process handles that refer to core files, zombie
45processes, and ELF objects.
