* wait.c (S_proc_wait: reap): Set *PID_STATUS to CHILD->p_pid.
Reported by Neal H Walfield <neal@cs.uml.edu>.
|
|
* wait.c (sample_rusage): New function.
(S_proc_mark_exit): Call it.
|
|
* proc.h (struct proc): New members p_rusage, p_child_rusage.
* wait.c (rusage_add): New static function.
(alert_parent): Use it to add dead child's p_rusage into parent's
p_child_rusage.
(S_proc_wait): Fill *RU out param with CHILD->p_rusage, not just zeros.
Rewrote subfunction child_ready and its two callers into new
subfunction reap to reduce duplicated code.
