23 /* Description: This tests the rt_sigprocmask() syscall */
24 /* rt_sigprocmask changes the list of currently blocked signals. */
25 /* The set value stores the signal mask of the pending signals. */
26 /* The previous action on the signal is saved in oact. The value */
27 /* of how indicates how the call should behave; its values are */
28 /* as follows: */
29 /* */
30 /* SIG_BLOCK */
31 /* The set of blocked signals is the union of the current set*/
32 /* and the set argument. */
33 /* SIG_UNBLOCK */
34 /* The signals in set are removed from the current set of */
35 /* blocked signals. It is okay to unblock a signal that is */
36 /* not blocked. */
37 /* SIG_SETMASK */
38 /* The set of blocked signals is set to the set argument. */
39 /* sigsetsize should indicate the size of a sigset_t type. */
40 /* */
41 /* RETURN VALUE:i */
42 /* rt_sigprocmask returns 0 on success; otherwise, rt_sigprocmask*/
43 /* returns one of the errors listed in the "Errors" section. */
44 /* */
45 /* Errors: */
46 /* -EINVAL */
47 /* sigsetsize was not equivalent to the size of a */
48 /* sigset_t type or the value specified in how was */
49 /* invalid. */
50 /* -EFAULT */
51 /* An invalid set, act, or oact was specified. */
