8 * Testing sending invalid signals to sigaddset().
9 * After invalid signal set, sigaddset() should return -1 and set
10 * errno to indicate the error.
11 * Test steps:
12 * 1) Initialize an empty signal set.
13 * 2) Add the invalid signal to the empty signal set.
14 * 3) Verify that -1 is returned, the invalid signal is not a member of
15 * the signal set, and errno is set to indicate the error.
