Примеры (Examples)

Sending a Signal to All Other Members of a Process Group
       The following example shows how the calling process could send a
       signal to all other members of its process group. To prevent
       itself from receiving the signal it first makes itself immune to
       the signal by ignoring it.

           #include <signal.h>
           #include <unistd.h>
           ...
               if (signal(SIGUSR1, SIG_IGN) == SIG_ERR)
                   /* Handle error */;

               if (killpg(getpgrp(), SIGUSR1) == -1)
                   /* Handle error */;"
