17.Sh NAME
18.Nm Pupdate_syms
19.Nd update cached symbol tables
20.Sh SYNOPSIS

22.In libproc.h
23.Ft void
24.Fo Pupdate_syms
25.Fa "struct ps_prochandle *P"
26.Fc
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. In general, the
38.Sy libproc
39library takes care of managing the need to call this function;
40however, debuggers, introspection tools, and others that are
41interposing on rtld activity may need to call this function. Note that
42the
43.Fn Pupdate_syms
44function is only meaningful for active processes. It will do nothing on
45process handles that refer to core files, zombie processes, and ELF
46objects.
