27.Sh DESCRIPTION
28The
29.Fn Pupdate_syms
30function is used to update all of the cached symbol tables in the
31process handle
32.Fa P :
33updating, invalidating, and caching new symbol tables as appropriate for
34functions such as
35.Xr Psymbol_iter 3PROC .
36This is generally called in response to activity by the run-time
37link-editor.
38In general, the
39.Sy libproc
40library takes care of managing the need to call this function;
41however, debuggers, introspection tools, and others that are
42interposing on rtld activity may need to call this function.
43Note that the
44.Fn Pupdate_syms
45function is only meaningful for active processes.
46It will do nothing on process handles that refer to core files, zombie
47processes, and ELF objects.
