KILLPG(2)           UNIX Programmer's Manual            KILLPG(2)

NAME
     killpg, killbkg - send signal to process group

SYNOPSIS
     killpg(pgrp, sig);

     killbkg(pgrp, sig);

DESCRIPTION
     _K_i_l_l_p_g sends the specified signal to all processes in the
     process group headed by process _p_g_r_p.  _K_i_l_l_b_k_g does the
     same, but only for processes that have not been marked by
     _s_u_b_m_i_t(2).

     Use of these calls is restricted to the super-user.

RETURN VALUE
     Upon successful completion, a value of 0 is returned.  Oth-
     erwise, a value of -1 is returned and _e_r_r_n_o is set to indi-
     cate the error.

ERRORS
     _K_i_l_l_b_k_g will fail and no signal will be sent if any of the
     following occur:

     [EINVAL]            _S_i_g is not a valid signal number.

     [ESRCH]             No process can be found corresponding to
                         the process group specified by _p_g_r_p.

     [EPERM]             The caller is not the super-user.
