  17 .Sh NAME
  18 .Nm Pupdate_maps

  20 .Sh SYNOPSIS
  21 .Lb libproc

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