10 * Testing invalid signals with sigismember().
11 * After invalid signal set sigismember() should return -1 and set
12 * errno to indicate the error.
13 * Test steps:
14 * 1) Initialize a full signal set.
15 * 2) Check for invalid signal from the full signal set.
16 * 3) Verify that -1 is returned and errno is set to indicate the error.
