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