8 This program tests the assertion that if the info parameter is not NULL,
9 then the selected signal number shall be stored in the si_signo member.
10
11 1. Register signal SIGTOTEST with the handler myhandler.
12 2. Block signal SIGTOTEST, and then raise it causing it to become pending.
13 3. Call sigwaitinfo() with only SIGTOTEST in set.
14 4. Verify that info.si_signo equals SIGTOTEST.
