10 * Testing sending invalid signals to sigdelset().
11 * After invalid signal sent, sigdelset() should return -1 and set
12 * errno to indicate the error.
13 * Test steps:
14 * 1) Initialize a full signal set.
15 * 2) Remove the invalid signal from the full signal set.
16 * 3) Verify that -1 is returned, the invalid signal is not a member of
17 * the signal set, and errno is set to indicate the error.
