8 * This program tests the assertion that if sigwaitinfo() was called and that
9   no signal in set was pending at the time of the call, then sigwaitinfo()
10   shall be suspended until a signal in set becomes pending.
11
12  Steps:
13  1. In the child process, register SIGTOTEST with handler.
14  2. call sigwaitinfo() with SIGTOTEST in set.
15  3. From the parent process, send a SIGTOTEST using kill.
16  4. Verify that the return value of the child is PTS_PASS, which indicates
17     that sigwaitinfo() has returned from it's suspended state.
