Example #1

File: ssl_master.c Project: zetafunction/pennmush-mirror

void
kill_ssl_slave(void)
{
    if (ssl_slave_pid > 0) {
        WAIT_TYPE my_stat;

        block_a_signal(SIGCHLD);
        kill(ssl_slave_pid, SIGTERM);
        mush_wait(ssl_slave_pid, &my_stat, 0);
        unblock_a_signal(SIGCHLD);
        close(ssl_slave_ctl_fd);
        ssl_slave_pid = -1;
        ssl_slave_state = SSL_SLAVE_DOWN;
    }
}

Example #2

File: info_master.c Project: zetafunction/pennmush-mirror

/** Kill the info_slave process, typically at shutdown.
 */
void

      block_a_signal(SIGCHLD);
      closesocket(info_slave);

      info_slave_pid = -1;
      unblock_a_signal(SIGCHLD);
    }
