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.
