Example 89 (page 395) provides an example of SIGALRM handling. It creates two threads that
wait for a SIGALRM signal. The SIGALRM signal is delivered to the correct thread, and the
sighand1() and sighand2() functions define the actions to be taken. Sample output:
sigaction for thread1 returned 0
sigaction for thread2 returned 0
Signal received for thread1 is 14
sigsuspend for thread1 returned -1
sigwait returned 0
sigwait for thread2 returned for signal 14
