7
8 * General API test of the raise() function.
9 * Test calling raise with the following values:
10 * - MINIMUM valid (in this case SIGABRT signal)
11 * - MAXIMUM valid (in this case SIGXFSZ signal)
12 * Item with POSIX default action as T - SIGALRM
13 * Item with POSIX default action as A - (done - SIGABRT)
14 * Item with POSIX default action as I - SIGCHLD
15 * Item with POSIX default action as S - SIGTSTP
16 * Item with POSIX default action as C - SIGCONT
17 *
18 * Error conditions:
19 * Boundary values for int
20 * MIN INT = INT32_MIN
21 * MAX INT = INT32_MAX
22 * MIN INT - 1 = 2147483647 (this is what gcc will set to)
23 * MAX INT + 1 = -2147483647 (this is what gcc will set to)
24 * unassigned value = -1073743192 (ex. of what gcc will set to)
25 * unassigned value = 1073743192 (ex. of what gcc will set to)
26 *
27 * Steps:
28 * 1) Set up signal handlers for all valid signals
29 * 2) Call all valid signals and verify they are received.
30 * 3) Call all invalid signals and verify raise() returns 0 and sets
31 * errno to EINVAL.
32 *
33 * Note: This test case maps to multiple assertions: 1, 2 (implicitly),
34 * 5, 6, 7, so it was given a large number as a file name.
