| 7 | !!DESCRIPTION | ||
| 2 | PerryLorier | 8 | __Killpg__ sends the signal ''sig'' to the process group ''pgrp''. See sigaction(2) for a list of signals. If ''pgrp'' is 0, __killpg__ sends the signal |
| 9 | to the sending process's process group. | ||

| 2 | PerryLorier | 12 | The sending process and members of the process group must have the same effective user ID, or the sender must be the super-user. As a single special case the continue signal [SIGCONT] may be sent to any process that is a descendant of the current process. |
