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