NAME

       /proc/tid/children - child tasks

DESCRIPTION

       /proc/tid/children (since Linux 3.5)
              A space-separated list of child tasks of this task.  Each child task is represented by its TID.

              This  option  is intended for use by the checkpoint-restore (CRIU) system, and reliably provides a
              list of children only if all of the child processes are stopped  or  frozen.   It  does  not  work
              properly  if  children of the target task exit while the file is being read!  Exiting children may
              cause non-exiting children to be omitted from the list.   This  makes  this  interface  even  more
              unreliable than classic PID-based approaches if the inspected task and its children aren't frozen,
              and most code should probably not use this interface.

              Until  Linux  4.2,  the presence of this file was governed by the CONFIG_CHECKPOINT_RESTORE kernel
              configuration option.  Since Linux 4.2, it is governed by the CONFIG_PROC_CHILDREN option.
