- _K_i_l_l_p_g sends the signal _s_i_g to the process group _p_g_r_p. See
- _s_i_g_v_e_c(2) for a list of signals.
-
- 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.
