| /* Description: This tests the rt_sigprocmask() syscall */ |
| /* rt_sigprocmask changes the list of currently blocked signals. */ |
| /* The set value stores the signal mask of the pending signals. */ |
| /* The previous action on the signal is saved in oact. The value */ |
| /* of how indicates how the call should behave; its values are */ |
| /* as follows: */ |
| /* */ |
| /* SIG_BLOCK */ |
| /* The set of blocked signals is the union of the current set*/ |
| /* and the set argument. */ |
| /* SIG_UNBLOCK */ |
| /* The signals in set are removed from the current set of */ |
| /* blocked signals. It is okay to unblock a signal that is */ |
| /* not blocked. */ |
| /* SIG_SETMASK */ |
| /* The set of blocked signals is set to the set argument. */ |
| /* sigsetsize should indicate the size of a sigset_t type. */ |
| /* */ |
| /* RETURN VALUE:i */ |
| /* rt_sigprocmask returns 0 on success; otherwise, rt_sigprocmask*/ |
| /* returns one of the errors listed in the "Errors" section. */ |
| /* */ |
| /* Errors: */ |
| /* -EINVAL */ |
| /* sigsetsize was not equivalent to the size of a */ |
| /* sigset_t type or the value specified in how was */ |
| /* invalid. */ |
| /* -EFAULT */ |
| /* An invalid set, act, or oact was specified. */ |
