  22 .Sh SYNOPSIS

  28 .Sh DESCRIPTION
  29 The
  30 .Fn Pupdate_maps
  31 function is used to verify that all of the cached mappings in the
  32 process
  33 .Fa P
  34 are still valid and update the cached data with any new information.
  35 This is generally called in response to activity by the run-time
  36 link-editor.
  37 In general, the
  38 .Sy libproc
  39 library takes care of managing the need to call this function; however,
  40 debuggers, introspection tools, and others that are interposing on rtld
  41 activity or other actions, may need to call this function.
  42 Note that the
  43 .Fn Pupdate_maps
  44 function is only meaningful for active processes.
  45 It will do nothing on process handles that refer to core files, zombie
  46 processes, and ELF objects.
